Olsen twin Mary-Kate is stepping out on her own for her first major acting role without sister Ashley.
The Two Of A Kind beauty is set to star alongside Mary-Louise Parker, who plays the lead role of Nancy Botwin, in at least 10 episodes of the hit U.S. programme.
The 20-year-old will appear as Tara, a devoted Christian teenager living in the religious community of Majestic, who becomes a love interest for Silas (Botwin's son), played by Hunter Parrish.
Olsen tells the Hollywood Reporter, "I'm thrilled to be a part of the show. It's really an honour to be a part of such a talented group of actors and writers."
Executive producer Jenji Kohan adds: "'Weeds' isn't your eight o'clock family fare. 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."
