Mary-Kate Olsen is in the Weeds

The younger half of the Olsen wonder twins has landed a role in the Showtime dramedy Weeds, says Reuters. Mary-Kate Olsen will appear in 10 of the 15 episodes of season three and play a church girl who becomes a love interest of Silas Botwin, played by Hunter Parrish.

Mary-Kate Olsen's appearance in Weeds is significant for a few reasons. It is her first major role without her twin sister, Ashley Olsen, and her first television appearance since she cohosted Saturday Night Live in 2004.

It's also a departure of material for the multimillionaire, who has typically been cast in kid-friendly fare. Weeds follows the life of suburban pot-dealer Nancy Botwin, played by Mary-Louise Parker.

Households were first introduced to the Olsen twins on Full House, where the nine-month-olds doubled up to play the show's too-cute baby, Michelle Tanner.

Also joining the cast of Weeds next season are Matthew Modine and Carrie Fisher. Season three begins this August.
