The Real Housewives of New Jersey star Danielle Staub emerged victorious Friday, when the teenaged daughter of costar Jacqueline Laurita was found guilty in a New Jersey municipal court of assaulting Staub following a hair-pulling incident last November.
Laurita’s daughter, Ashley Holmes, 19, will have to pay a fine of $189.
In December, Staub, 45, testified that a hair extension was ripped out by an angry Holmes during a fight at a benefit at the North Jersey Country Club.
Staub had also filed complaints against Laurita and costar Teresa Giudice, claiming they cursed and threatened her, but she later dropped the complaints.
A source tells PEOPLE that Staub, whose book The Naked Truth is due out in May, is pleased with the ruling. “She feels great, of course,” the source says. “Ashley was found guilty of assault.” –David Caplan
