The last time Britney Spears modelled for American clothing firm Candie's, observers noticed picture editors had been a bit too heavy-handed with the airbrush.

But after completing a gruelling 97-date world tour last November, Britney's body is looking more honed than ever, leaving little need for digital enhancement.

Returning as the face of Candie's for the second time, the mother-of-two looks stunning as she flaunts her curves in a floral lingerie two-piece.

For the Spring/Summer 2010 ads, Spears was photographed by three of the world's top photographers Annie Leibovitz, Mark Seliger and Terry Richardson for three very different shoots.

In the Richardson shoot, the 28-year-old cuddles up to a fuchsia teddy bear against a white background as she pulls a suggestive pose in a floral bra, matching frilly hipster knickers and peep-toe heels.

In a separate shot by Leibovitz, who frequently photographs A-listers for Vanity Fair magazine covers, the singer flips her hair in a more fun pose as she sits on a chair in a black dress with a beaded Aztec neckline.

Spears' final shoot of the day saw the singer posing for Seliger on the most elaborate set, a Moulin Rouge-style dressing room.

Against a backdrop of feather boas, flowers and lots of pink, Spears gets to flaunt her curves in a series of tight-fitting clothes, including a hot pink vest and skinny jeans and a black camisole.
