Mary-Kate Olsen is making a television comeback with a role on the Showtime hit Weeds. The Full House alum will play appear in ten episodes next season as Tara, a devoted Christian girl who becomes a love interest for Mary-Louise Parker character Nancy Botwin's son on the show. "I'm thrilled to be a part of the show," Olsen says. "It's really an honor to be a part of such a talented group of actors and writers." Matthew Modine is also set to join the show next year. "Weeds isn't your 8 o'clock family fare," says the series creator. "It's an adult show with adult subject matter, and we're confident Mary-Kate is right for the role. She came in and read with Hunter and was absolutely charming and real and seemed like a great fit. Audiences have seen only one side of Mary-Kate, but here we'll see her in a whole new light."
