SHARON OSBOURNE is under police investigation after allegedly scuffling with a contestant on her US reality TV show Rock Of Love: Charm School.
MEGAN HAUSERMAN claims the rock matriarch assaulted her during a recording of the show's reunion special on Saturday.
Osbourne is said to have flipped when Hauserman insulted her by saying she is only famous because of her marriage to Black Sabbath singer OZZY OSBOURNE.
The rock matriarch allegedly ran across the stage, grabbed Hauserman by the hair, and scratched her.
According to reports the pair had to be pulled apart by security guards.
Hauserman went to hospital the following afternoon and filed a report with the Los Angeles Police Department that night.
Authorities have confirmed Osbourne is a suspect in a minor battery allegation but that no charges have been filed.
