TRENTON, N.J. (AP) -- A New Jersey mother once featured on the reality show "Wife Swap" has been accused of stabbing her husband.

Jamie Czerniawski (zur-nee-OW'-skee) tells The New York Post it was self-defense. Her husband's lawyer denies that.

She is charged in Monmouth County with aggravated assault and is free on $75,000 bail.

According to court papers, the former Miss Teen New Jersey used a kitchen knife to slash her husband, Charles, in their Freehold home on Memorial Day weekend.

She tells the newspaper that her husband became jealous when she got a phone call from a mutual male friend.

The couple were featured on "Wife Swap" in 2006. The suspect swapped places with a mom from Arizona who is a tattooed freak show performer.
