Sharon Osbourne is currently under investigation by the LAPD after a contestant on her reality show accused the rocker wife of attacking her and sending her to the hospital.

Megan Hauserman, a 26-year-old contestant on “Rock of Love: Charm School” claims Osbourne pulled her hair violently and scratched her on the recent reunion episode until security managed to pull her off.

According to the Daily Mail, Osbourne, 56, reportedly lost it when Hauserman said she was merely famous for managing a “brain-dead rock star,” in reference to her husband Ozzy Osbourne.

Hauserman went to the hospital Sunday afternoon and later filed a police report that same night, TMZ said.

Osbourne is no stranger to fighting. According to the Mail, she threw a glass of water at a co-star when he made a joke about her husband. She also admitted to sending her own excrement in Tiffany jewelry boxes to a journalist who criticized her children, accompanied by a note reading “I heard you’ve got an eating disorder. Eat this.”
