S Club 7 star Paul Cattermole has expressed his delight after bidding for his Brit Award on eBay reached £66,000.
The 40-year-old, who said he had "bills to pay", placed an advert on the site for the Britannia statuette, which he won with the band for best newcomer in 2000.
The singer from St Albans, Hertfordshire, soon waived the postage fee as the bidding suddenly shot up.
Cattermole wrote on eBay: "I didn't expect it to skyrocket like this. I am watching every bid very closely."
He continued: "If there are some silly bids at the end on Monday I will be deleting them and/or coming straight down the line to the next bidder. So you can bid with full confidence.
"Postage can now be ignored. I will cover the full cost of postage with the most secure carrier."
The performer, who has offered to meet the winning bidder and take photos, has insisted he was not "dissing" the band by selling the award.
Cattermole first announced he would be selling the statuette on Twitter and posted a picture captioned "opportunity knocks".
He has also listed on eBay a frame complete with a metal plaque, which he received for S Club 7's album going platinum in New Zealand. The start price remains at £200 but no bids have yet been made.
The Never Had a Dream Come True singer later retweeted fans after the news of his eBay listing went viral.
"Oh mate, it sucks that you've got to do this. I'd buy in a heartbeat if I could. Loved your tour 2016, do it again and we'll buy tickets :). Hope things work out for you," said one.
