Is a battle between Hollywood's biggest couples about to go down?!
It sure sounds like that might be stirred up after Katy Perry did a little diss slinging during an appearance on Ellen DeGeneres' show!
KatyKat lashed out her claws a little when John Mayer crashed her interview, and all three got to talking about Who You Love vs. Kanye West's Bound 2, featuring Kim Kardashian.
But don't worry, it wasn't all cat fighting during the interview because the super cute twosome also chatted Christmas gift plans and John's romantic side!
It's totes adorbz!!
Ch-ch-check out the HIGHlarious and sweet interview (above)!
