$189. It’s the price of exacting apparent revenge on a Real Housewife of New Jersey!

Ashley Holmes, the 19-year-old daughter of The Real Housewives of New Jersey star Jacqueline Laurita, has been found guilty of assaulting co-star Danielle Staub.

A municipal court ordered Holmes to pay a minimal fine, stemming from a hair-pulling incident last November.

Judge Lawrence Katz said Holmes was guilty of one count of assault from the complaint by Staub.

Prosecutor Tom Melani said Holmes will have to pay a fine of $189, which includes the $33 court cost.

“I was glad the cameras didn’t show and the proceedings took place like any other proceedings in courts.” Melani said.

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.
