Rashida Jones (The Office) has joined the cast of NBC's untitled comedy starring Amy Poehler.

According to Variety, NBC and producers continue to keep a tight lid on the Poehler sitcom, but some details are starting to emerge. Jones is set to play Ann Logan, a nurse whose boyfriend has a strange injury. It's that injury that leads Jones' character into the world populated by Poehler and Aziz Ansari (who was the first thesp attached to the project, back when it was still, indeed, an Office spinoff).

Although rumors that Jones would be a part of the show had been flying for months, the net hadn't confirmed her casting until now.

For Jones, it's a reunion with The Office exec producers Greg Daniels and Mike Schur, who are also creating the new Poehler skein. Thesp played Karen Filippelli, the love interest of Jim (John Krasinski), on season three of Office.

Jones said she's been told not to reveal too much about the show -- and that Daniels and Schur have even been tight-lipped in giving her information.

Producers haven't yet set a shoot date for the first episode, but Jones said she expected to report to work sometime in early 2009. NBC has said the Poehler skein will be ready by spring, but there's no definite date lined up yet -- and the skein could be pushed to fall.
