Sharon Osbourne has allegedly come to blows with a model who reportedly called her husband Ozzy ‘brain dead’.

Megan Hauserman, 29, filed a police report claiming Sharon ran across the stage after she insulted her husband, grabbed her by the hair, and refused to let go.

The former X Factor judge flew off the handle at a taping of the VH1 show Rock Of Love: Charm School after the two traded verbal insults, showbiz website TMZ.com reported.

On the programme, which is hosted by Sharon, 14 contestants from the reality show Rock Of Love compete to develop proper etiquette in order to win 100,000 dollars (£65,300).

The website showed Megan, a former Playboy model best known for her reality show appearances on Beauty and the Geek, Rock of Love and I Love Money, leaving hospital after the assault, holding her left arm in a sling.

A spokeswoman for the Los Angeles Police Department confirmed officers had received a report and were investigating the incident but no one has been charged.
