Lily Allen And Elton John Get Into Catfight At London's 'GQ' Men Of The Year Awards

Pop icon reportedly called out his young co-host for drinking too much during the show.

Lily Allen and Elton John got into a verbal scuffle while co-hosting Tuesday's GQ Men of the Year Awards at London's Royal Opera House, The Times of London reports.

The music veteran called out the 23-year-old pop singer for swearing and slurring her way through her dialogue as she drank champagne, according to the Times. "What, you are going to have another drink?" John asked.

That's when the real catfight got under way. "F--- off, Elton," Allen responded, while celebs like TV chef Gordon Ramsay, producer Mark Ronson, actress Thandie Newton and model Elle MacPherson looked on. "I'm 40 years younger than you. I have my whole life ahead of me."

John, 61, quipped, "I could still snort you under the table."

Allen then tried to play it off, saying, "I don't know what you are talking about."

She continued to steal the spotlight when Tony Bennett took the stage to accept the Inspiration Award. As John introduced the 82-year-old crooner, Allen announced, "I'll still f--- him."

Later in the night, Allen had some good news for the press. She revealed that her younger brother, actor Alfie Owen-Allen, is engaged to actress Jaime Winstone, introducing her as "my very soon-to-be sister-in-law."

At the magazine's annual ceremony, Led Zeppelin took home an Achievement Award for their comeback concert, Ronson received the Maverick Award, and Primal Scream were named Band of the Year.
