Mama Drama on 'Relative Madness'

The tough-as-nails British mum presides over one of the more famous dysfunctional families in rock. Thanks to MTV’s “The Osbournes,” the whole world was privy to the foul-mouthed antics of house of Ozzy and their many small dogs. Since the show aired, both Kelly and Jack Osbourne have attended rehab, and Sharon has battled colon cancer. Most recently, Sharon has appeared as a judge and mentor on the UK reality TV talent show “The X Factor.”
