Was Katy Perry REALLY Going To Throw Her Coke In Kara's Face? "Yes!"

I'm loving Katy Perry even more by the minute!

The pop star - who's engaged to Brit funnyman Russell Brand - was a guest judge on American Idol last night and got into a fight with Kara DioGuardi about a contestant...

Kara liked the guy's singing AND was moved by his touching story. But Katy said to Kara, "This is not a Lifetime movie, sweetheart. You have to have talent!" And later when Kara began to sing Katy's hit song "I Kissed a Girl," Katy cut her off with the following: "Please stop before I throw my Coke in your face!"

So, when an X17 photog saw Ms. Perry going to the gym this afternoon, he asked her if she was seriously about to do it... and Katy responded with "yes!" Damn, we missed a cat fight.

Watch the vid above!



So catty, Katy.
