It's your chancee to own Robbie's tiger pants. They're G-r-r-r-rotty!...

ROBBIE WILLIAMS has contributed a total of 120 personal items to a charity auction being hosted by SOTHEBYS to raise funds for COMIC RELIEF and his own GIVE IT SUM charity.

It is anticipated the sale will raise around £70,000 and includes hand-written lyrics to his 1997 chart smash ‘Angels’, the ‘Rock DJ’ tiger underpants, the lunchbox used in the ‘Millennium’ video, and the lavatory on wheels that was used on his UK tour, complete with number plate BOG 2000.

Other items include model Gisele’s spangled Union Jack bikini she wore on the cover of Vogue in a photo shoot with Wiliams, his double bed and a guitar.

A spokesperson for Sothebys told the London Evening Standard that they were unsure what to expect from the sale: “In terms of pop memorabilia auctions, Robbie is an unknown quantity, but as he is the biggest male solo star in Britain and probably Europe, I would imagine the demand for the items will be very strong. I wouldn’t be surprised to see the lyrics for ‘Angels’ going for a very high price.”

The auction takes place on April 10. For more details [url=]
