Although we’re still not sure whether Sharon Osbourne is a hair-puller, one thing was definitely made clear last night: the Osbourne matriarch will not tolerate insults about her family.

During yesterday’s Rock of Love Charm School reunion special, the 56-year-old did a fairly decent job keeping her interjections to a minimum while Megan Hauserman blathered about getting her dog fixed. Unfortunately, one of Sharon’s remarks didn’t sit well with the former contestant.

After hearing that she “shouldn’t be allowed to breed,” Megan told Osbourne that the only thing she’s managed to do as a celebrity was take care of her ‘brain dead rock star husband.’ (You can cue the video to the 1:20 mark now.)

If you believe the police report filed after the taping, Sharon didn’t just launch a drink. She also allegedly assaulted Hauserman and pulled her hair. Unfortunately, the security members - and the careful editing - prevent us from seeing that on camera.

No charges have been filed thus far.
