Mary-Louise Parker could handle posing naked in a publicity photo for her offbeat Showtime comedy series Weeds. It was the snake that bothered her.
"I didn't think I was going to do it actually," the actress, 43, tells the Associated Press. "But then, they were there and the snake was there, and I didn't want the snake to win, so I put the snake on."
Parker is photographed from the back with a snake coiled around her shoulder and down her bare back, head poised mid-strike.
"I've been naked quite a bit, actually," says Parker. "You Google me, you'll see it all."
But she adds: "I grew to really love the snake – by the end of the day."
The third season of Weeds, which also stars Kevin Nealon, Elizabeth Perkins and new-to-the-series Matthew Modine, premieres Monday night, followed by the series premiere of Californication, which stars David Duchovny who is sometimes shown in the snake ad series – and not appearing to be wearing much, either.
As for Parker, she stars as a widowed suburban mother who starts selling marijuana to support her family.
