Watch out, Liz Lemon!
Denise Richards is set to appear on NBC's 30 Rock, the actress confirmed via Twitter Wednesday.
"So excited!! I'm going to be doing an episode of #30Rock! one of my favorite shows!!!!!" Richards, 40, wrote.
The actress, author and mom of three's new role comes on the heels of a successful arc on Spike TV's Blue Mountain State, where she appeared as Debra.
There's no word yet on when Richards' 30 Rock episode will film or air -- season six is set for a 2012 premiere, delayed by series star Tina Fey's second pregnancy.
