Ozzy and Sharon Osbourne are doing some house-cleaning.

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

The auction, taking place on November 30th, will also feature items from their MTV reality show, "The Osbournes," including a pair of Ozzy's trademark round-rimmed glasses.

"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."

With their three children now grown and out of the house, the couple have changed their style and moved to a new home.
