Mary-Kate Olsen hits "Weeds": Here's the vid clip

Here it comes, the debut of a second actress with a hyphenated Mary- name on Showtime's "Weeds."

As evidenced by this clip kindly provided by Showtime (click right here), former tot-star Mary-Kate Olsen makes her grownup TV debut in the Sept. 17 seg of "Weeds," playing the fundamentalist Christian hottie Tara Lindman in a 10-episode arc --- which basically means the remainder of the Emmy-nominated skein's third season.

The Tara character is, of course, a love interest for Hunter Parrish's Silas (pictured at left with Olsen), the older son of Mary-Louise Parker's drug-dealing soccer mom character, Nancy Botwin. As Tara tells Silas in their first meeting, when he inquires about the hood ornament-size cross hanging around her neck, "I'm tight with the Lord," but she also appreciates the pleasures of smoke. And eye makeup.
