"American Idol" judge Paula Abdul will be laying down the law on a new TV series.

Abdul will play a courtroom judge when she guest stars in September on the Lifetime original series "Drop Dead Diva," about a vain model whose departed soul ends up in the body of an intelligent, full-figured attorney, says People.com.

Abdul's judge presides over a case in which a shop declines to stock its shelves with plus-sized clothes.

Other stars set to guest on the show, which debuts July 12, include Liza Minnelli, Nia Vardalos, Rosie ODonnell, Tim Gunn and Delta Burke, says People.
