Lily Allen was reportedly thrown off Flavio Briatore's yacht.
The 'Smile' singer enraged the Formula 1 boss with her drunken antics in Cannes, France, which included ripping her bikini top off and having to be rescued from the sea.
Lily, who appeared to be intoxicated, jumped overboard the vessel but had to be dragged out of the sea by crew members who feared she was drowning.
When she was back on board, embarrassed Flavio made her cover up before asking her to leave.
The incident is the latest in a string of drunken antics for the singer, who is in the French resort for the world famous Cannes Film Festival while she takes a break from recording her second album.
Last week, topless pictures of Lily sunbathing were released, but the pop star laughed off the shots, insisting she was happy to be a pin-up.
On Friday (16.05.08), she stunned fellow partygoers by revealing she wasn't wearing any underwear at a black tie party.
The day before, she apparently fainted in a taxi back to her hotel, having to be carried out by her father Keith, who is in Cannes promoting his new film.
A friend of the singer said earlier in the week:
"Lily doesn't give a damn. She just wants to have fun. She couldn't care less what people think, she's just a young girl having a good time"
Lily had had a turbulent start to the year, following her tragic miscarriage in January and subsequent split from her Chemical Brothers star boyfriend Ed Simmons.
