Lily Allen had to leave early from the GQ Men of the Year Awards in London, as she was reportedly too drunk to stay.
The drama started when Allen started rambling loudly when Madonna was presenting the Inspiration of the Year Award.
One audience member told the Daily Mail: "Lily was being rude and loud, she was chatting all of the way through and it was painfully obvious.
"At first nobody noticed but then it was evident what she was doing - even Madge gave her a look."
Later the singer reportedly fell over so her record label staff stepped in and suggested she left.
"Lily was drunk and wasn't quite aware of what she was doing. It was felt best that she left there before any real trouble started," the source added.
