MTV mom Sharon Osbourne underwent surgery Wednesday for a treatable form of cancer. An Osbourne family spokesperson declined to say what type of cancer Ozzy's wife is battling, but she's expected to make a full recovery. "She has the loving support of her husband and three children who are by her side at this time," the rep said in a statement. It's unclear what impact all of this will have on the upcoming second season of MTV's The Osbournes.
