A signed Britney Spears T-shirt is expected to fetch $20,000 at auction.
The garment carries the line 'I Love You Grandma’ which was scrawled by Britney when she wore it while appearing in 'The New Mickey Mouse Club’ as a child. It also features the signatures of her co-stars, Justin Timberlake and Christina Aguilera.
In total, seven items of Britney’s clothing are being offered to the public by online auctioneers Gotta Have It! but the T-shirt is expected to generate the most interest.
Gotta Have It! owner Ed Kosinski commented: "Something like that has never come up for auction before. We expect it to go for between $15,000 and $20,000."
The other Britney items – which were provided by Tri Star Sports and Entertainment group on the 26-year-old’s behalf – include costumes from her 'Drive Me Crazy’ and 'Oops, I Did it Again’ tours, a blue and white Santa dress she wore in a Christmas Pepsi ad in 2000, and the orange coat and trousers she wore to the Billboard Music Awards earlier that year.
Some of the proceeds will go to charity.
Also included in the Rock and Roll Pop Art auction are Marilyn Monroe’s jeans from her film 'River of No Return’, which had been a gift to Britney from designer Tommy Hilfiger.
The jeans are expected to top the predicted bids for Britney’s clothes, and could fetch at least $60,000.
There are a further 500 items up for auction, including one of Elvis Presley’s jumpsuits and Madonna’s personal diary from 1987-1988.
Explaining the diary – predicted to fetch at least $6,000 – Ed said: "It is all handwritten and what she did day-to-day – if she had dinner, if she had rehearsals.'
He added that it even includes phone numbers for the 'Material Girl’ singer’s then-husband Sean Penn and her 'Dick Tracy’ co-star Dustin Hoffman. The online auction will be open from July 21 until August 6.
