Weeds to go, Dude!

Mary-Kate Olsen going solo for “Weeds”

It’s not April 1st, right? Ya sure?

Hmm. OK…

According to The Hollywood Reporter, Mary-Kate Olsen will leave her sister Ashley home alone whilst she does a stint on the very un-“Full House”-y series, “Weeds”.

50% of the showbiz powerhouse unit will appear in at least ten episodes of the hit Showtime series, says the trade.

On the Lionsgate-produced show, Olsen will play Tara, a devoted Christian girl living in the newly developed megachurch community Majestic who becomes a love interest for Nancy Botwin’s (Mary-Louise Parker) son Silas (Hunter Parrish).

“I’m thrilled to be a part of the show,” Olsen said. “It’s really an honor to be a part of such a talented group of actors and writers.”

“Weeds” marks Olsen’s first major solo role. Since their debut on ABC’s hit comedy series “Full House” at age 9 months, Olsen and her twin sister, Ashley, have starred together in a string of kids and tween-oriented series and movies for television and video.

” ‘Weeds’ isn’t your 8 o’clock family fare,” series creator and executive producer Jenji Kohan said. “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.”

In addition to Olsen, joining the “Weeds” cast this upcoming season is previously announced Matthew Modine.
