The LAPD is investigating an alleged brutal cat fight that went down between Sharon Osbourne and a contestant on the VH1 reality show "Rock of Love: Charm School" who ended up in the hospital.





Megan Hauserman claims Sharon Osbourne went ballistic during a taping of the show's reunion special Saturday night. She says Sharon O. ran across the stage of the show, grabbed Megan by her hair and would not let go. She says Sharon (who is the host of the show) continued to pull to pull at her hair and scratch her until security eventually separated the two. Megan went to the hospital Sunday afternoon and filed a report with the LAPD on Sunday night.

We're told Sharon's nonsensical hubby Ozzy was the cause of the beat down. According to Megan, she responded to a crack Sharon made about her by saying Sharon is only famous for managing a brain dead rock star. That's what set Sharon off.

The LAPD says Sharon is a suspect in a minor battery. No charges have been filed.

Calls to VH1 and Sharon's management company were not returned.
