The first official photos of Katy and Taylor were at the MTV VMAs in 2008.
Back in the days of “Love Story” and “I Kissed a Girl” success, the two would hang out up at parties, such as this 2009 Grammys event.
Katy told Taylor she deserves all the awards and that she's an angel.
Taylor was keen to share the mad love for Katy's Waking Up In Vegas. And Katy was dead grateful for her kind words.
Swift tweeted a photo of her and Perry, writing that her pal “really puts the ‘fun’ in Fundon.” She also uploaded another version of the photo covered in cats.
Perry tweeted back, “LYLAS! C u @ the VMA’s bbgirl! (TS is an angel!)
Swift attended Perry’s birthday bash that year, and by all accounts, it was epic. She was very, very grateful and tweeted out her appreciation.
The two reunited yet again at the 2010 Grammys, where they posed for photos and made funny faces, having fun together!
Katy Perry stopped by Swift’s Fearless tour and joined Taylor on stage as an impromptu guest during her stop at the Staples Center in LA. They sang "Hot N Cold."
She also tweeted about it, writing, “Katy! LA! I will always love you!” She said always, guys.
Swift beat out Perry for the 2011 American Music Award’s Artist of the Year honor – but Perry was totally happy for her and congratulated her with a big hug.
Back in the day, Taylor Swift had a brief romance with musician John Mayer and when they abruptly split, she allegedly wrote 'Dear John', on her 2010 album Speak Now, about their brief relationship.
Katy and John then started dating in 2012, shortly after the disintegration of the Katy's marriage to Russell Brand, and briefly rekindled their relationship a couple of years later. n early 2015. They also reportedly had a Disneyland date together in May.
In 2016, though, Katy seems to have moved on from John to date Orlando Bloom. The two most recently popped up together in Cannes, but they've been going strong all, year long.
Things may have really started to take a turn when three of Katy's 'California Dreams' world tour dancers received a place on Taylor's 2012 world tour promoting her Red album.
One dancer, Lockhart Brownlie, claimed that during the tour with Taylor, Katy's people reached out to see if he and two other dancers (Scott Myrick and Leah Adler) would perform on the world tour for Katy's album Prism, released in 2013 – the only drawback being that they would have to leave Swift's tour before its completion. All three agreed to these terms.
Lockhart said he had a better relationship with Katy, and that he wasn't doing much dancing during Taylor shows, so he was keen to get stuck into the Prism tour.
Speaking to Australian daily newspaper The Examiner, Lockhart explained: "Obviously we were with Katy for two and a half years, she's like family to us. So we were, like, 'Absolutely'. We weren't really dancing in Taylor's tour anyway, so I had got a little bored and I really wanted to do a promo tour."
On what it was like to work with Taylor, he continued: "Taylor is very untouchable. When we did see her, we had so much fun with her, but she's a lot more protected than Katy.
"Katy's 28 now and can do her own thing. Her team are so lovely, so we have such a good connection. And this time around she is a lot more in control."
Lockhart and fellow tour dancers were treated to a fun-filled Independence Day with Taylor, which she blogged about on her own website.
But shortly after their decision to switch shows, Taylor stopped following them on Twitter and they were removed from her tour.
The first sign of a feud came during Taylor's interview with Rolling Stone magazine in 2014.
Taylor divulged details of her crumbling relationship with an unnamed female celebrity.
"For years, I was never sure if we were friends or not. She would come up to me at awards shows and say something and walk away, and I would think, 'Are we friends, or did she just give me the harshest insult of my life?'
"She did something so horrible. I was like, 'Oh, we're just straight-up enemies'. And it wasn't even about a guy! It had to do with business.
"She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me. And I'm surprisingly non-confrontational - you would not believe how much I hate conflict. So now I have to avoid her. It's awkward, and I don't like it.
"I know people will make it this big girl-fight thing. But I just want people to know it's not about a guy."
When asked about that tweet in her cover story with Billboard right before her 2015 Super Bowl halftime show performance, Perry simply said, “If somebody is trying to defame my character, you’re going to hear about it.”
Swift finally addressed the alleged feud with Perry by, well, not addressing it. “I’m not giving them anything to write about,” Swift told The Telegraph. “I’m never going to talk about her in my interview. It’s not going to happen.”
She also got really real about having friends and enemies. “It’s not real if someone appears to never have any issues with anyone,” she said. “I have my friends. I have enemies. I have bad days when I don’t want to go to a photo shoot, but I’m not going to show up four hours late. I’m going to be there on-time. I’m not nice all the time, but I try not to be carelessly rude to people who don’t deserve it.”
The long anticipated “Bad Blood” music video premiered, and it was as epic as we all expected … and also did very little to squash rumors that the song was about Perry, considering Swift’s enemy in the video is played by Gomez in a dark wig with blunt bangs.
Swift kind-of-sort-of-accidentally involved herself in a heated Twitter exchange with Nicki Minaj after MTV Video Music Awards nominations were announced. Minaj, who wasn’t nominated for video of the year, tweeted out, “If your video celebrates women with very slim bodies, you will be nominated for vid of the year.”
Some people thought this was an attack on Swift – including Swift herself. She replied, “I’ve done nothing but love & support you. It’s unlike you to pit women against each other. Maybe one of the men took your slot..”
Minaj was quick to reply – and deny – that she was casting any shade. “Huh? U must not be reading my tweets. Didn’t say a word about u. I love u just as much. But u should speak on this.”
Swift was quick to call a truce as she finished the exchange on a friendly note, saying: “If I win, please come up with me!! You’re invited to any stage I’m ever on.”
The following day, Katy weighed in with her own take, a clear reference to her history with the singer.
Katy seemed to be accusing Taylor of being hypocritical, seeing as Bad Blood was apparently written about the breakdown of her former friendship with Katy.
And its star-studded music video (featuring Lena Dunham, Ellie Goulding and Selena Gomez) be could be interpreted as Taylor reinforcing who she's got in her corner.
As for reports in June 2015 that Katy had registered a track called '1984' (in an apparent nod to Taylor's latest album 1989, rather than the George Orwell novel), her reps told Digital Spy it's not even her track and had nothing to do with Taylor, adding: "Katy Perry was not involved in writing, singing, recording or registering this song."
But in 2016, there were signs of peace between the pair when Katy put Taylor on the A-list guestlist for a private pre-Grammys party called "An Evening to Celebrate the Creators". The Spotify-sponsored event was for musicians only. And, of course, both turned out for the Met Gala that same year, where Taylor was co-chair.
Earlier in the day, Taylor reportedly claimed a writing credit on the new Calvin Harris song, "This Is What You Came For." This inspired Calvin to rant about Taylor on Twitter; he even mentioned Katy by name. Her Hillary Clinton GIF dropped shortly after that.
She then retweeted an old tweet from May 2015:
Following her first fragrance "Mad Potion," Perry introduced the fragrance "Mad Love." Thinking back to the "Bad Blood" lyrics, "Cause baby now we got bad blood / You know it used to be mad love," this definitely seems like more than a coincidence.
Perry caused a veritable Internet frenzy when she responded to a tweet about the possibility of collaborating with Swift. When one user tweeted, “Will you collab with Taylor swift,” the pop star responded with: “If she says sorry, sure!”
At a Kanye West concert in Inglewood, California, Perry added more fire to the alleged feud. As West rapped his controversial “Famous” lyrics (“I feel like me and Taylor might still have sex”), Perry recorded herself dancing along enthusiastically.
She then zoomed in closer at the most controversial lyric, which the crowd sang along with him: “I made that bitch famous!
In an exclusive interview with Entertainment Weekly, Perry opened up about her album and whether it had a follow-up to Swift’s “Bad Blood,” which was rumored to be about Perry. The “Roar” singer said her album was “very empowered” and that “there is no one thing that’s calling out any one person.”
“One thing to note is: You can’t mistake kindness for weakness and don’t come for me. Anyone. Anyone. Anyone. Anyone,” Perry said. “And that’s not to any one person and don’t quote me that it is, because it’s not. It’s not about that. Honestly, when women come together and they decide to unite, this world is going to be a better place. Period end of story.”
She continued: “But, let me say this: Everything has a reaction or a consequence so don’t forget about that, okay, honey. [Laughs] We got to keep it real, honey. This record is not about anyone else! This record is about me being seen and heard so that I can see and hear everyone else! It’s not even about me! It’s about everything that I see out there that I digest. I think there’s a healing in it for me and vulnerability. If people want to connect and be healed and feel vulnerable and feel empowered and strong, God bless and here it is.”
Perry dropped a surprise new song featuring Nicki Minaj called “Swish Swish,” and her fans think it’s the response to Swift they’ve been waiting for.
“Don’t you come for me/No, not today/you’re calculated/I’ve got your number/Because you’re a joke/and I’m a courtside killer queen,” go Perry’s lyrics.
"You're about as cute as an old coupon, expired" … "Karma's not a liar, she keeps receipts" … "So keep calm, honey. Imma stick around for more than a minute. Get used to it!" … "Funny my name keep coming out your mouth, 'cause I stay winning"
Minaj’s rap verse includes more lyrics that sound directed at Swift, with whom she previously had a Twitter disagreement: “Don’t be tryna double back/I already despise you/All that fake love you showin’/couldn’t even disguise you.” Fans also pointed out Minaj might be referencing longtime rival Remy Ma in another line: “Silly rap beefs just give me more checks.”
After the song dropped, the “Shake It Off” singer’s close friend Ruby Rose slammed Perry on Twitter, writing, “I just think with everything going on in the world to go from rebranding as a political activist only to ditch it and go low.. is.. a bummer.”
After much speculation, Katy dropped by The Tonight Show and explained the true meaning behind the lyrics after Jimmy asked if the song featuring Nicki Minaj song is "about anyone we know." “I think it’s a great anthem for people to use whenever someone’s trying to hold you down or bully you," she explained “It’s a liberation from all the negative that doesn’t serve you.”
Perry went on the record with her side of the story during her Carpool Karaoke segment on The Late Late Show With James Corden, telling the host that Swift sparked their feud. “There’s a situation. Honestly, it’s really like she started it, and it’s time for her to finish it,” she said, explaining, “It’s about backing dancers, there were three backing dancers. I tried to talk to her about it and she wouldn’t speak to me.”
“I do the right thing any time that it feels like a fumble,” Perry continued. “It was a full shutdown and then she writes a song about me, and I’m like, ‘OK, cool, cool, cool, that’s how you want to deal with it? Karma!’ ”
After Corden asked if “the beef would ever be off the grill,” Perry responded, “What I want to say is that I’m ready for that BS to be done. Now, there is the law of cause and effect. You do something, there’s going to be a reaction, and trust me, daddy, there’s going to be a reaction. It’s all about karma, right? I think personally that women together, not divided, and none of this petty bulls–t, women together will heal the world.”
In an interview with NME, Katy tried to explain why she brought up the feud at all with James Corden. "Well, [Late Late Show host] James Corden makes me and the whole world feel very safe," she said. "No one has asked me about my side of the story, and there are three sides of every story: one, two, and the truth." She went on: "I mean, I'm not Buddha — things irritate me. I wish that I could turn the other cheek every single time, but I'm also not a pushover, you know? Especially when someone tries to assassinate my character with little girls [her fans]. That's so messed up!"
Taylor's team announced that she would be returning her extensive music back catalog to streaming services, including Spotify, at midnight on June 9, the same time as Katy's Witness was set to drop. The news was shared via Instagram on Thursday as a "thank you" to fans for helping her 2014 album 1989 sell over 10 million copies.
Taylor famously removed her music from all streaming services — in a move that many considered the opposite of a "thank you" to fans — shortly before 1989 was released. In 2015, she wrote a letter to Apple Music explaining why she wouldn't be streaming 1989 on its new platform, and shortly after, the company made changes to its policy and Taylor "happily" changed her mind. Up until now, Apple Music has been the only place to listen to her music, and the timing of her move was pretty peculiar, considering it was just hours before Katy's new album was released.
We're calling shade.
Especially with the two now conveniently fighting it out on the Spotify front page for pop queen supremacy too.
