Paul Cattermole has expressed his delight after bidding for his S Club 7 Brit award reached £66,000.
Cattermole, 40, has been attempting to sell the statuette that he won with his then-bandmates for best newcomer in 2000.
After the bidding on eBay suddenly shot up, Cattermole waived the postage fee.
"I didn't expect it to skyrocket like this. I am watching every bid very closely," he wrote on the eBay bidding page.
"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."
He added on the listing: "Postage can now be ignored. I will cover the full cost of postage with the most secure carrier."
The Don't Stop Movin' singer, who has offered to meet the winning bidder, previously told Newsbeat: "I don't want the other members to think that I am dissing the band by selling it but there are bills to pay."
