The Rachel: Jennifer Aniston to Guest Star on "30 Rock"

It might not be Oprah, but NBC has landed another mighty big fish to guest star on Season Three of comedy 30 Rock.

Jennifer Aniston (Friends) will guest-star in an upcoming episode of 30 Rock as Claire Harper, Liz Lemon's stalker/former roommate from Chicago who turns up unannounced in Manhattan and attaches herself to Jack Donaghy.

"Jennifer is not only incredibly lovely to have around, she also has what the young people would call 'mad skills,'" said 30 Rock creator/executive producer/star Tina Fey in a statement. "We're very excited that she's joining us."

"What a thrill to have Jennifer back on NBC on a Thursday night. She is the perfect comedic talent to work with the Emmy-winning 30 Rock cast," said Teri Weinberg, Executive Vice President, NBC Entertainment. "This promises to be a memorable, hilarious night of comedy."
30 Rock returns with brand new episodes on October 30th ay 9:30 pm ET/PT on NBC.

Stay tuned.
