At the GQ Men of the Year awards in 2008, Elton John and Lily Allen fell out in front of thousands when John made a snide remark about Lily Allen's drinking habits.
The pair were co-hosting the awards but when Ms Allen said: '...and now the most important part of the night', Elton chipped in with 'What? Are you going to have another drink?'
Feisty Allen fired back: 'F*** off Elton. I am 40 years younger than you and have my whole life ahead of me!'
Ouch! We wouldn't want to get on the wrong side of Elton!
