Amanda Peet gave birth to a healthy baby boy last night in Los Angeles.

This will be the third child for the 42-year-old actress and her husband, 'Game of Thrones' co-creator, David Benioff, 44. They also have two daughters, Frances, 7, and Molly, 4.

Pregnancy seemed to be smooth sailing for Amanda, who said things were going "great" just two months before giving birth to her first son.

"I can't complain. I mean, I'm tired but otherwise, I'm doing really well," she said.

No baby name has been revealed as of yet -- but we're anxious to find out! Congrats to the happy family!
