The civil lawsuit was filed in Los Angeles Superior Court Monday by Megan Hauserman, 29, who appeared with Osbourne on the cable channel VH1's show "Rock of Love: Charm School."

Hauserman was a guest on the television show on Dec. 13 when Osbourne attacked her by pulling her "hair out of her head" and scratching her, forcing Hauserman to seek care at a hospital, according to the lawsuit.

The incident aired on VH1 in January and took place after the two women traded insults over Ozzy Osbourne.

Osbourne's representatives were not available to comment.

On the show, Osbourne served as a headmistress to former contestants from another reality series, "Rock of Love," who after competing for rock singer Bret Michaels' affections get lessons from Osbourne in etiquette and moderation.

Hauserman's lawsuit accuses Osbourne of battery and emotional distress and seeks unspecified damages, money for loss of income and medical costs.

Osbourne, 56, is a fixture of reality TV, and has appeared as a judge on the show "America's Got Talent" and British show "The X Factor," as well as a show that depicts her life as the wife of heavy metal icon Ozzy Osbourne.
