Sharon Osbourne, 56, who is married to the "Prince of Darkness," may be crowned the "Princess of Darkness" if the reports we’re hearing about a "brutal" brawl between her and a 27-year-old reality television actress is true. TMZ is reporting that during a taping of a VH1 reunion reality television show, host Sharon Osbourne attacked contestant Megan Hauserman after she called her famous husband Ozzy a "brain-dead rock star."

According to TMZ:

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 that Mrs. 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 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.

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

London’s Daily Mail reports how Osbourne ridiculed the aspiring actress during the filming of the series, which aims to transform the tawdry into the tasteful. Hauserman was kicked off "Charm School" in an episode broadcast in November.

Speaking about Hauserman after she was evicted, Osbourne said: "She said her ambition was to be a trophy wife. Oh God. Well she has got the f**king brain of a peanut. She does have a pretty damn good body, but no f**king brain. Her brain is between her legs."
