Mary-Kate Olsen: WEEDS! WEEDS! WEEDS!

Mary-Kate Olsen takes a break on a Hollywood set on Friday after shooting scenes for Showtime’s hit show Weeds.

Mary-Kate plays Silas’ (played by Hunter Parrish) new leading lady, girl-next-door Tara Lindman. She says she plays “a good Christian girl,” whose wardrobe will always include a cross… but she still gets high on a little herb.

Says creator Jenji Kohan, “[Tara] is comfortable with her Christianity and her recreational drug use. We’re not necessarily poking fun at religion. We’re poking fun at the commerce of religion.”

The former Full House star will be featured in 10 of the shows in the upcoming third season, which premieres on Monday, August 13.
