Island Def Jam teamed up with Stand Up To Cancer at this year's Sundance Film Festival, where celebrity guests signed a fabulous Vespa S50 at the label's VIP lounge. The auction is being hosted by Charity Folks and net proceeds benefit SU2C.

Considering the line-up of celebs who signed the adorable Vespa, the auction will certainly garner a nicely sized price tag, but if you have some spare change lying around, head over to www.charityfolks.com/su2c to bid to win this one-of-a-kind Sundance collectible.

Celebrity signers include: Alan Cumming, Andie MacDowell, Anne Heche, Christie Brinkley, Dominic Cooper, Hoobastank, Robin Thicke, Terrell Owens and Wesley Snipes.

Act fast—the auction began Tuesday, January 27, 2009 and ends Tuesday, February 10, 2009!
