Sharon Osbourne, wife of rocker Ozzy Osbourne, has been accused of coming to blows with a contestant on her reality television show about etiquette.
Model Megan Hauserman, 29, who appeared on the VH1 show "Rock of Love: Charm School," filed a police report accusing Osbourne of pulling her hair on Saturday at a taping of the program after the two traded verbal insults, celebrity Web site TMZ.com said.
Officer Kate Lopez, a spokeswoman for the Los Angeles Police Department, confirmed that police had taken a report.
"We know Sharon Osbourne was involved in some way, we just don't know how," Lopez told Reuters.
Hauserman has posed for Playboy on the Web, and she appeared in "Rock of Love: Charm School" earlier in the season.
The show centers on 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.
A spokeswoman for Osbourne, 56, declined to comment on the incident, and VH1 also did not immediately comment.
Osbourne is a fixture of reality TV, and has appeared as a judge on the show "America's Got Talent" and the British show "The X Factor," as well as shows that depict her life as the wife of heavy metal icon Ozzy Osbourne.
