Stars turned out in force last night to help uber producer Mark Ronson ring in his 33rd birthday.

The party, themed 'your favourite album cover', kicked off at Mayfair's Punchbowl pub before revelers were taken by coach to Hedsor House in Buckinghamshire.

Actress and girl about town Jaime Winestone led the pack  in a punk-themed costume, smoking cigarettes and swigging alcohol with rather convincing vigor.

Knees-up: TV presenter Nick Grimshaw reenacts Lily Allen's famous karate kick at photographers

TV presenter Nick Grimshaw came as party girl Lily Allen in a prom dress and sneakers, reenacting her famous karate kick at photographers while clutching a can of beer.

Comedian Alan Carr took the opportunity to slip into some lycra leggings, apparently channelling Madonna.

Musician Carl Barat paid tribute to Adam Ant, while Kate Moss' ex Jefferson Hack decided against dressing up, arriving instead in a demure grey suit and trench coat.

Ronson, the man of the moment, and girlfriend Daisy Lowe kept a low profile and managed to avoid being photographed on the night.

However the birthday boy wore a red wig, but an fellow party-goer confessed: 'I didn't get who he was supposed to be.'

Daisy 'looked stunning as Kate Bush in a leopard catsuit with crimped hair'.

Amy Winehouse was noticeably absent from the celebration following reports the pair still haven't made up after they fell out trying to record her doomed attempt at the theme song for forthcoming James Bond movie Quantum Of Solace.

It's been an eventful week for Ronson - he landed the Alfred Dunhill Maverick of the Year gong at the GQ Awards on Tuesday night.
