Lily Allen has been signed up as the new face and body of Agent Provocateur lingerie.

The singer - who recently slimmed down from a UK dress size 12 to a size 8 - will follow in the footsteps of Kate Moss, Maggie Gyllenhaal and Dita Von Teese when her campaign for the company, shot on Monday, is released next year.

An insider said: "The owners of Agent Provocateur, Joe Corre and Serena Rees, are delighted. They feel her natural look will appeal to a lot of women. She's in amazing shape since she lost the weight, and the pictures of her are absolutely incredible."

Lily - who reportedly received a whopping six-figure sum for the deal - has put her weight loss down to hypnosis.

She said recently: "After the hypnotism I want to go to the gym every day otherwise I feel really bad. I just want to get more toned and healthy. I'm really good at the moment - I've never been happier."

And the 22-year-old singer also credited new boyfriend Chemical Brothers star Ed Simons for helping her shed the weight, giggling: "Me losing weight is down to love. I probably shouldn't say the word love, actually. I'm in 'like'. We like each other a lot!"

But Lily insists she will never take her weight loss to extremes and has vowed to always stay a healthy weight.

She said: "I'll never be a size 0 catwalk model. I have absolutely no interest in that, at all."
