Since everyone loves a good cat fight, toofab is breaking down the most memorable star squabbles. Check out our top three worst celebrity feuds of 2014 below:
Taylor Swift is known for her usual love/ex-boyfriend songs, but her new song, "Bad Blood," stands out for it's angrier tone and darker lyrics. Rumor has it, the track is about her mega-fight with Katy Perry.
The "Blank Space" singer admitted the single was about another female artist, telling Rolling Stone, "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?'"
Last year, T. Swift said the popular pop star really crossed the line. "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."
Perry allegedly tried to hire back some of Swift's dancers, leading most to assume the song is about her.
Next up? Kim Kardashian vs. Naya Rivera.
It seems the "Glee" star didn't think much of Mrs. West's decision to pose naked on the cover of Paper magazine -- and she wasn't shy about making her opinions known.
"I normally don't. But...you're someone's mother..." she commented on Kim's Instagram post, which displayed the naked cover shot above.
Kim didn't respond to Naya's remark ... she was too busy trying to "break the internet."
And the battle between Justin Bieber and Orlando Bloom got downright physical! Back in July, Bloom allegedly attempted to punch Bieber while in Ibiza, Spain.
Rumors of the Biebs' flirtation with Bloom's ex-wife Miranda Kerr and a photo of Orlando with Justin's ex-girlfriend Selena Gomez fueled the fight.
The best part? A slew of celebs chimed in after the punch was thrown to pick a side. Sorry Bieber, Orlando got you beat there too.
