Elton John and Lily Allen get in a catfight on stage

Elton John and Lily Allen were both extreme bitches to each other on stage at the GQ Men of the Year Awards in London on Tuesday. Lily was sauced up, drinking champagne and slurring her words while onstage with him, which pissed Sir Elton off. And that's where the fun started.

Elton: What, you are going to have another drink?
Lily: F*ck off Elton, I'm 40 years younger than you. I have my whole life ahead of me.
Elton: I could still snort you under the table.
Lily: F*ck off, I don't know what you're talking about.

Now call me crazy, but Elton John is a legend in the music business. I don't think I'd exactly tell him to "f*ck off" in front of a huge audience of people. But then again, Lily Allen is bat sh*t crazy, so I'd expect nothing less.
