Do you think you've got what it takes to be the next Amy Winehouse?

We're talkin' about the voice, not the trainwreck personal life.

If so, who better to know than the "Rehab" hitmaker's Grammy-winning producer, Mark Ronson?

Ronson's review of an aspiring artist's music is just one of the many celeb items being auctioned off by Fashion Rocks to benefit Stand Up to Cancer starting Friday at eBay.com/fashionrocks.

If singing ain't your thang, there's plenty more to choose from, including:

A 16" x 20" portrait of Justin Timberlake taken by celebrity photographer Craig McDean
A leather jacket worn and autographed by Keith Urban
Two tickets to a Diane von Furstenberg fashion show
Tennis rackets signed by James Blake, Venus Williams and Maria Sharapova
A Duffy concert package, including a meet and greet with the singer

Meanwhile, I'm told Josh Groban, Billy Crystal, James Taylor and Sugarland have just signed on to appear at Friday's megawatt celebrity Stand Up to Cancer benefit. The hourlong show will be simulcast live and commercial-free from Hollywood's Kodak Theatre on CBS, ABC, NBC and E!.
