Photographs of Victoria Beckham clad only in a bra and knickers and heels have been unveiled in a new advertising campaign for Emporio Armani.

Looks like Madonna’s Louis Vuitton ads have some competition.

Adriana Lima is pictured here wearing the world’s most expensive bra, costing a whopping $5million.

The Victoria’s Secret’s Black Diamond Miracle Bra is adorned with 3,900 precious gems, tiny black diamonds, 117 one-carat round diamonds and 34 rubies. On the top, it’s designed to offer a maximum cleavage lift.

Adriana stripped off for an ad promoting Victoria’s Secret’s new fragrance, VS Wish. “Whether her sexy poses will entice ladies to purchase the perfume remains questionable, But at least her male fans can enjoy looking.”

Pop star Shakira sold one of her bras for $3,000 at a charity auction on Sunday (10Feb08).

The Latin beauty sold more than 40 stage costumes from her 2007 Oral Fixation tour to raise funds for her Bare Feet Foundation, which is leading a project to build a school for impoverished kids in her native Colombia.

Among other items up for sale on the eBay Giving Works website included a low cut red dress with large, wing-like sleeves, a blue tank top baring the slogan ‘For Those Who Love to Rock’, and a lavender skirt with turquoise and coral beading, which went for $1,000.
