Thumbs Up For Sharon Osbourne

Sharon Osbourne, wife of British heavy metal icon Ozzy Osbourne and co-star of the MTV reality series "The Osbournes," underwent surgery Wednesday for a treatable cancer.

Family spokeswoman Lisa Vega wouldn't say what type of cancer Osbourne has or where the surgery took place, but said it was completed by early evening.

"Everyone is in good spirits because the prognosis is very positive," said Vega. "The doctors have told them all she's expected to make a full recovery. Obviously, they're concerned for their mother and are by her side, but they're all looking forward to a positive outcome."

"The Osbournes," the highest-rated program in MTV's history, chronicles the unorthodox home life of Ozzy, Sharon, and two of their three children - 17-year-old daughter Kelly and 16-year-old son Jack. Thursday is the couple's 20-year wedding anniversary.

Vega said the entire family - including their 18-year-old daughter, Aimee, who doesn't appear on the show - was at the hospital for the operation.

Vega said Osbourne, 50, would stay in the hospital for at least the night and possibly longer.

MTV released a written statement Wednesday, saying: "We know Sharon will conquer this with the same tenacity and vibrancy she approaches everything else in her life. Our thoughts are with Sharon and the entire Osbourne family and we send her our love and support for a complete recovery."

Because of the surgery, the first two dates of Osbourne's Ozzfest 2002 summer music tour, in Bristol, Va., and Pittsburgh, have been postponed.

A second season of "The Osbournes" is scheduled to begin airing in the fall. It will consist of 20 episodes, twice as many as the first season.

MTV, like CBSNews.com, is part of the Viacom corporate family.
