Rock matriarch and reality TV star Sharon Osbourne has been accused of attempting to run over a court official with her car.

The wife of rocker Ozzy Osbourne is being sued by reality show contestant Megan Hauserman, who alleges she was attacked by Osbourne after appearing on her TV series Rock of Love: Charm School last December.

Osbourne is said to have lost her temper when Hauserman insulted her husband, calling the musician a "brain-dead rocker."

Hauserman filed suit for battery, negligence and infliction of emotional distress in a Los Angeles court in March, but now she's levied new charges against Osbourne, claiming the 56 year old assaulted a process server when he tried to deliver legal papers to her on April 20th.

According to TMZ.com, the Rock of Love contestant filed new documents at Los Angeles County Superior Court in August, in which she alleges the process server "approached and was almost run over by defendant (Osbourne) to the point where the papers were dislodged from the process server's hand."
