It's another girl for Amanda Peet! - which first broke the news of Peet's pregnancy - can exclusively reveal that she is expecting a daughter.

While at the Sundance Film Festival - where Peet, 38, premiered the comedy Please Give on Jan. 22 - the actress showed off her baby bump and was overheard telling pals, "We're having a baby girl!"

In 2007, Peet and her husband of three years, screenwriter David Benioff, welcomed their first child, Frances "Frankie" Pen, whom Peet named after her mother, Penny.

Last year, she told Parade she hopes her daughter doesn't grow up too fast.

"I'm trying not to think about what the world will be like when she grows up," she said. "I think more about when is she going to start drinking and wearing a G-string and how can I stop those things from happening."
