EXCLUSIVE: In what amounts to her most substantial acting role so far, Kim Kardashian has signed on to costar in The Marriage Counselor, the Lionsgate film Tyler Perry will next direct, based on his stage play. Shooting begins October 26 in Atlanta. The film tells the story of Judith, an Ivy League-educated relationship expert who makes her living dispensing marital advice, but is so bored with her own marriage that she breaks her professional code and cheats with a smooth talking client only to realize she has made a huge mistake. Jurnee Smollett plays the marriage counselor and Kardashian will play Ava, a co-worker who gives Judith a big city makeover and new confidence as she struggles with her personal issues. Kardashian previously played roles in the films Deep in the Valley and Disaster Movie.
