Why do you think Sharon Osbourne, was so nasty to gentle Susan Boyle?
I guess Sharon’s insecurities got the best of her. I didn’t know some celebrities resorted to such activity. Possibly some just see anyone else in show business as a threat or competitor, and as such, have some sort of uncontrollable urge to attack. Maybe its something similar to a wild animal’s instinct to kill. They just look for a weakness in another and lunge at it. But in the final analysis, it could be that Sharon insulted herself too. She was the only one who expressed knowledge of what a hairy asshole looks like. Makes you wonder what she does in her spare time.
