Denise Richards, James Marsden head to '30 Rock'Add to Favorites | 30 Rock
But the show won't be out of commission forever -- especially after the recent flurry of casting news.
Denise Richards will appear on the upcoming run. The 40-year-old actress confirmed the news on Twitter Wednesday (Oct. 5), though there's still no word on the role she'll be playing.
"So excited," she writes. "I'm going to be doing an episode of 30 Rock! One of my favorite shows!" [Editor's note: we removed a few of her exclamation points, as it's pretty clear how she feels.]
Richards most recently appeared on Spike TV's "Blue Mountain State."
Also joining "30 Rock" is James Marsden. THR reports the actor, who recently guested on "Modern Family," has booked six episodes of the series -- which makes us think he'll almost definitely be a love interest for Liz Lemon.
"30 Rock," which returns in early 2012, will also include the another appearance from "Up All Night" star Will Arnett as Devon Banks.
For the record: An earlier version of this story stated Denise Richards had a cameo on the Season 9 premiere of "Two and a Half Men. She was asked to appear but did not.
