Teresa Giudice has no idea who Janice Dickinson is in dramatic ‘House of Villains’ Season 2 trailer

Teresa Giudice had no idea who Janice Dickinson was when the former “America’s Next Top Model” judge walked onto the set of E’s “House of Villains” Season 2.

In a dramatic new trailer released Tuesday, the “Real Housewives of New Jersey” star, 52, appears confounded when Dickinson, 69, sauntered through the door of the cast’s luxe Los Angeles digs for a cameo.

“What’s your name?” Giudice asks from the top of a staircase.

A shocked Dickinson — who often touts herself as the world’s “first supermodel” — then replies, “You don’t know who I am?”

While it isn’t shown what happens next between the women, the clip teases another surprise celebrity appearance — from none other than Tori Spelling.

The “Melrose Place” alum storms onto the show dressed in sexy teacher attire comprising a pink crop top, black mini skirt, fishnet stockings, platform heels and eyeglasses.

“This is my classroom, so you better follow my rules,” she says during what appears to be some sort of learning exercise. “Or else!”

The sneak peek also sees Spelling, 51, furiously cracking her ruler against the desk, causing the group of reality TV villains to gasp in horror.

The sophomore installment of “House of Villains” features an eclectic group of notorious unscripted personalities.
