She may be the host of Rock of Love Charm School, but apparently Sharon Osbourne could use a refresher course herself.
E! News has confirmed that a police investigation has been launched after Osbourne allegedly attacked a contestant on the VH1 show, scratching her face and pulling her hair during a reunion taping on Saturday.
"We know a battery incident is alleged to have occurred on a taping of a reality show Sharon Osbourne hosts," said Los Angeles police spokesman Ben Llewellyn. Llewellyn would not confirm whether a police report had been filed.
Asked if she planned to comment, Osbourne rep Nicole Perna said, "We do not."
Megan Hauserman, 26, purportedly drew Osbourne's ire after commenting on camera that she was only famous for managing her husband, whom Hauserman dubbed "a brain-dead rock star."
Back for the reunion special, Hauserman, who is a regular reality contestant and previous winner on Beauty and the Geek, was booted from Charm School after four episodes for kicking a fellow contestant.
Ironically, Osbourne's final words before expelling Hauserman may come back to haunt the host: "The one thing I cannot stand is violence."
