"Salma is truly a gifted talent and an incredible force in our industry," said Teri Weinberg, Executive Vice President, NBC Entertainment. "I've had the privilege of working with her and I can't wait to see what comedic sparks fly with our brilliant '30 Rock' cast."
"I have been a fan of Tina's talent, both as an actress and a writer, since working with her years ago on 'SNL.' I am so excited to be part of such an intelligent, funny show, as well as working with the brilliant Alec Baldwin and the rest of the cast of '30 Rock,'" said Hayek.
"Salma is smart, funny, and gorgeous. I think she will be a great strong presence opposite Jack Donaghy," said Emmy Award-winning Tina Fey, creator, executive producer and star of "30 Rock."
"30 Rock" premieres on October 30 (Thursday, 9:30-10 p.m. ET).
