Given Lily Allen's recent antics, Damien Hirst might have felt a little nervous about inviting her to one of the biggest celebrations of his career.

Only two weeks ago, her appearance at the GQ Men Of The Year awards descended into chaos as she downed glasses of wine onstage - and insulted co-host Elton John.

But the Shine singer appeared to be on her best behaviour at the artist's bash at Sotheby's auction house on Friday night.

She arrived dressed in a demure black dress, immaculate makeup and high heels - and spent the night chatting to showbiz friends including superstar producer Mark Ronson.

Lily, who has been making far headlines for all the wrong reasons lately, was the perfect party girl at Hirst's star-studded bash, which celebrated his largest body of work to be seen and auctioned under one roof.

The artist famed for creating a storm in the art world with his works featuring dead animals preserved in formaldehyde also invited a host of Brit DJs providing the musical backdrop for the night.

Among the guests, which numbered more than 1,000, were Mark Ronson, Bono, Ali Hewson, Jo Wood, Jaime Winstone and Alfie Allen.

Dressed in a sweet 50s-style full-skirt black frock and sweet pink lipstick, Lily was ever the lady all night.

And while her friend and producer Mark Ronson enjoyed what was on offer from the bar, Lily appeared to be steering clear from the drinks and opting for what looks like a fruit salad cup.

She and Mark later got behind the decks to entertain party-goers.

Hit the decks: it was a night of Brit DJ sets

Earlier this month the 23-year-old singer hit the headlines because of her tipsy behaviour and constant sipping of champagne while co-hosting the GQ Men of the Year Awards with Elton John.

When Allen told the audience at London's Royal Opera House "now we reach a very special point in the evening," Sir Elton John replied: "What, you are going to have another drink?"

In control: Lily seemed to be shunning the punch for the night

Lily responded: 'F*** off Elton, I'm 40 years younger than, I have my whole life ahead of me.'

The 61-year-old veteran retorted: 'I could still snort you under the table' before she told him: 'F*** off. I don't know what you are talking about.'

However Lily played down on the spat, writing on a separate MySpace post: 'Elton and I exchanged jokes and there were no hard feelings at all, in fact neither of us gave it a second thought.'

In June Allen had to be carried out of the Glamour Women Of The Year Awards and later claimed: 'I can't believe I got into that state.

'I believe somebody put something in my drink. It's totally not in my repertoire to do something like that.'

However, judging by her angelic behaviour on Friday, Allen appears to have put her hard-partying days behind her.
