Former Ally MCBeal star, Jane Krakowski has revealed that her new show 30 Rock is expecting some cool new guest appearances during its new series.

“People are fans now, so they’re asking to be on,” star Jane Krakowski said at a party for Intermix on September 6. “Megan Mullally’s on, Jennifer Aniston’s on, Steve Martin’s coming on.”

Rumours are also circulating that Oprah Winfrey and even some of the the Gossip Girl stars might appear, too. Gossip Girl and 30 Rock both shoot at Silvercup Studios in New York. “I finally got to meet Blake (Serena) and Penn (Dan),” Krakowski said. Does that mean we will see them on 30 Rock this year? “I don’t know if it’s official,” she said. “I just said hello to them over coffee.”
