Posh Rocs

After a summer-long campaign to crack America by hitting the chat show and party circuit with husband David, Victoria Beckham is now trying an even more direct approach.

The former Spice Girl has stripped down to her underwear and high heels for a new ad campaign with Rocawear, the clothing label owned by Beyoncè Knowles's rapper boyfriend Jay-Z.

With its baggy tracksuits and trainers, the brand is usually associated with the drugs and violence world of gangsta rap. However, the association will benefit both parties. While Posh will help give the label respectability, her profile will be raised by her link to the R&B superstars.

She is due to release a hip-hop inspired album, produced by Rocawear co-owner Damon Dash, who signed her to his Roc-A-Fella record label.
