American Pie alum Natasha Lyonne has been booked for the hour-long series finale of Weeds, according to The Hollywood Reporter.

Lyonne will play a woman named Tiffani, but not much else is known about her role.

Weeds' Mary-Louise Parker on the series finale: "I cried when I read it"

Series star Mary-Louise Parker told reporters at Television Critics Association fall TV previews last week that she cried when she read the series finale. "I think [creator Jenji Kohan] just managed to bring things together in a way. ... She didn't make it a total happily-ever-after thing, but there was hope in it and there was some sort of benediction."

Lyonne, best known for the American Pie films and But I'm a Cheerleader, most recently guest-starred on New Girl and Law & Order: SVU.
