Elton John and Lily Allen went at it Tuesday night at the GQ Men of the Year Awards in London. The two stars were paired as presenters for the event, which was held at the Royal Opera House, but as the night went on and Allen's drinks kept a-flowin', Sir Elton could no longer hold his tongue.

Despite the 23-year old Allen's extravagant gown, her slurs, swearing and inability to stick to the script pushed her co-host over the edge, according to reports. As Allen swigged champagned onstage and announced, "...and now the most important part of the night," John snapped, "What? Are you going to have another drink?"

Allen replied with, "F--- off Elton. I am 40 years younger than you and have my whole life ahead of me!," as the shocked audience went quiet. A furious John fired back, saying, "I could still snort you under the table."

Not to be outdone, Allen responded again, saying,, "F--- off. I don't know what you are talking about."
