Let's hope that Jennifer Jason Leigh wasn't simply another woman that Andy banged (on a washing machine, in this case).

The actress was hilarious and ideally suited as Nancy's sister during her two episode run on Weeds. Will we see her again?

Hopefuily, says series creator Jenji Kohan.

"We loved having Jennifer on the show and were dazzled by her performance and her chemistry with our cast. We have no idea when she'll be back, but we'd love to have her return if our story and her schedule align. Fingers crossed."

Meanwhile, another big guest star will debut next week, on the episode titled "Van Nuys." Alanis Morisette comes aboard as Nancy's new obstetrician.
