After she welcomed daughter Penelope in August, Tina Fey spent a lot of time glued to her TV.

"I was on maternity leave for about nine days," the 41-year-old comic joked on Rock Center With Brian Williams Monday.

"You watch different stuff because you're up nursing in the middle of the night, and you watch Extreme Couponing and Cake Boss," she explained. "You know your maternity leave is about to end when you're like, 'Oh, I've seen this Cake Boss.'"

Fey -- who's also mother to daughter Alice, 6 -- added that she eventually grew tired of Bravo's Real Housewives franchise due to their constant bickering.

"I can only do New York and Beverly Hills," said Fey, who called the New Jersey cast "subhuman."

"Orange County, I literally can't tell the women apart. They look like a fire at a wax museum," Fey joked. "I can't tell what I'm looking at."

According to Fey, the appeal of Real Housewives has little to do with the castmembers' personalities.

"I'm a little worried about the Real Housewives franchise. I don't want them to fight all the time," the 30 Rock star told Williams, 52. "I just want to see their weird houses."
