Britney Spears is giving fans the chance to own the gown she wore in the billboards for her fragrance Radiance – to raise funds for a friend's sick son.
The "Toxic" superstar is auctioning off the silver backless dress she donned for the perfume's promotional posters on ebay.com in a bid to boost donations for the The Matthew Van Daff Special Needs Trust.
The charity was set up to raise money for the treatment of little Matthew, who was born with a brain injury after being starved of oxygen in the final days of pregnancy. The proceeds raised from the sale will help his parents provide round-the-clock care for their son.
On Spears' Facebook.com page, her assistant writes, "Such a great cause. Brit donated her dress from the Radiance ad to our friend David, who started a trust for his son with a brain injury. He put the dress up for auction & all proceeds will go to his son's cause."
Bids had reached over $4,000 as WENN went to press.
Britney's latest single, "Hold It Against Me," is also dominating the charts. This week, "Hold It Against Me" debuts at Number One on Billboard's Hot 100 Singles chart, selling 411K digital singles in the U.S. within just one week of its exclusive release on iTunes. This is the biggest first week track number for a female artist, the record was previously held by Taylor Swift. According to Billboard she's the second artist in the trade magazine's 52-history to "debut multiple songs at No. 1," and she "joining Mariah Carey as the only acts to arrive at No. 1 more than once."
