Amanda Peet is pregnant again!

The actress, 36, and her husband of three years, screenwriter David Benioff are expecting their second child, her rep tells exclusively.

In 2007, Peet -- who recently appeared in the sci-fi flick 2012 -- welcomed daughter Frances "Frankie" Pen, whom she named after her mother, Penny.

Peet has said motherhood is not what she expected.

"One surprise of motherhood for me was how little control I have," she told Cookie magazine last summer. "I thought it would be an extended, blissful romance with me at the helm, cuddling this little creature to life. It's been bittersweet and humbling to let her lead, and to try not to be perfect myself."

Last month, Peet 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."
