Osbournes auctioning off collectibles for charity

Ozzy and Sharon Osbourne are doing some housecleaning.

The 58-year-old rocker and his wife are selling art, furniture and collectibles from their homes in Malibu, Beverly Hills and England.

The Nov. 30 auction will also feature items from their MTV reality show, "The Osbournes," including son Jack Osbourne's black leather bedroom furniture and a cast-iron crucifix that adorned Ozzy's den in various episodes.

A portion of the proceeds will benefit the Sharon Osbourne Colon Cancer Foundation.

"It's time to unload," said Sharon Osbourne, who celebrates her 55th birthday on Wednesday. "We just have an overabundance of possessions that we do not need."
