Alanis was a Weeds fan before she earned a role on the show

She was only on screen for one scene in last night’s Weeds episode, but Alanis Morissette seemed right at home among the quirky characters in Ren Mar.

That might be because she’s been a fan of the series for years.

“Somehow, they make very fantastical things seem very mundane and commonplace, which I love,” she told USA Today.

Morissette cruised through viewings of previous seasons, watching them on her bus while on tour. She then sought a meeting with Weeds creator Jenji Kohan, who she ultimately convinced to cast her as OB/GYN Audra Kitson.

“Nancy is in a pickle, and Audra helps her outside of what typically would be allowed in a hospital,” Morissette said. From there, it’s just a hop, skip and a jump into all of the family’s drama — and into Andy’s bed.

While her songs won’t appear on the show (licensing costs a lot of CA$H) the Canadian singer-songwriter/actress said she’s likely to follow the muse musically and theatrically.

“I never think in terms of having to pick between two forms of expression,” she said. “I do the one that calls me the most.”
