Amanda Peet welcomes a baby boy!

Los Angeles - Amanda Peet has given birth to her third child.

The Whole Nine Yards actress and her husband David Benioff - with who she already has daughters Frances, seven, and Molly, four - welcomed a baby boy into the world in Los Angeles on Sunday, but his name has not yet been revealed.

The 42-year-old star surprised fans at the Emmy awards in late August when she debuted her baby bump as she had managed to keep the news under wraps for some time.

Amanda later revealed her pregnancy was "great" though she had been feeling tired.

She said: "It's great. I can't complain. I mean, I'm tired but otherwise, I'm doing really well."

The brunette beauty - who married her Game of Thrones showrunner spouse in 2006 - said Frances was excited about being a sister again, but admitted Molly was less impressed.

She said: "They're pretty excited. The older one is pretty excited, the middle one is not so sure."

Amanda's third pregnancy may also have surprised fans as she previously admitted she felt she would be "too old" to have a baby past the age of 40.

Speaking soon after she gave birth to Molly when she was 38, she said: "I'm really old. David was like, we have to wait three years. And I was like, we don't have three years! We'll be too old at that point."
