Johansson, who has appeared in an Avril Lavigne music video and on "The Tyra Banks Show," was arrested Thursday.

Cops have busted the stunning 23-year-old Swedish model for allegedly working as the "house mom" at a high-end midtown brothel they say was run by a prominent lawyer.

Sabina Johansson was charged with promoting prostitution at a dance club in NYC, according to court records.

While Johansson has publicly denied knowing about the sex-for-sale activities going on in the private rooms of the club, cops allege she was wise to the tricks.

NYPD vice unit officers posing as patrons claim Johansson greeted them at the club in April and told them they could expect more than lap dances from the strippers if the price was right. "Defendant told [the undercover officer] that she was aware prostitution activity was going on at the club in its private rooms," court records contend.

Johansson, a brown-haired beauty who proudly boasts of her 34-24-34 frame on her modeling Web site, worked at Big Daddy Lou's from January 2007 until she quit just days before cops raided the club July 17.

As the house mom, Johansson allegedly collected nightly fees of up to $80 from the club's 120 dancers, scheduled shifts and rented out the private rooms and suites, prosecutors claim.

Johansson was charged with a third-degree felony and released on her own recognizance. So far, 22 people, including four dancers, have been pinched in the probe.
