LOS ANGELES (Reuters Life!) - Victoria Beckham, a regular on lists of the best-dressed celebrities, is following the lead of her famous footballer husband and stripping down to her designer underwear for an advertising campaign.

Emporio Armani on Wednesday said Beckham, who came to fame as "Posh Spice" in the British pop group the Spice Girls, will model underwear for the company in an advertising campaign set to roll out in spring next year.

She joins her husband, British soccer star David Beckham, who was the focus of a similar Armani underwear campaign this past summer that caused a stir among his fans.

Victoria Beckham, 34, posed for the pictures in the ritzy beachside community of Malibu where she lives with her husband and their three young sons.

The images were shot by fashion photographers Mert Alas and Marcus Piggott, the same duo who took David Beckham's underwear ad pictures.

"Victoria is a style icon, a dynamic lady whose influence and recognition will add great excitement to the continued international growth of our Emporio Armani women's underwear business," Giorgio Armani, the Italian designer at the head of the company, said in a statement.

It's far from Beckham's first venture into fashion.

She has worked as a model and four years ago she designed her own line of high-end denim jeans for Rock and Republic. She has also marketed jeans under her own label, dVb.

The Beckhams moved to Los Angeles from Britain last year so David Beckham could play soccer for the L.A. Galaxy although he is now negotiating a short-term loan to play for AC Milan from next January.
