The funnywoman is among a number of stars who are putting bizarre gifts up for sale on eBay.com in aid of U.K. charity Comic Relief.
Wax’s auction, which had attracted bids up to $150 (£100) by Thursday (10Mar10), will give the winner the chance to attend a clinic and be present while she undergoes the face-freezing injections.
Other stars taking part in the sale include Pet Shop Boys singer Neil Tennant, who is offering his own keyboard, and Hot Fuzz actor Nick Frost, who will give the winning bidder a signed poster and a personal phone call.
In a separate eBay sale, other stars including Nicole Richie, Rosario Dawson, Bret Michaels and Lenny Kravitz are offering to link up with fans on microblogging website Twitter.com in aid of anti-poverty charity CARE USA.
They have agreed to ‘follow’ the highest bidders for a minimum of 90 days, and some will even mention the auction winners in a ‘Tweet’.
