Two days after our photogs caught pregnant Amanda Peet beaming in Beverly Hills with her four-year-old daughter Molly June at her side -- the Something's Gotta Give star and husband David Benioff, co-creator of Game of Thrones, welcomed their third child, named Henry Peet Friedman Benioff, on Sunday.

In addition to her son, the 42-year-old actress has two daughters, Molly June and a seven-year-old, Molly Pen.

In October the former Studio 60 on the Sunset Strip star told People mag, “[My daughters] are very excited now ... We’ll see what happens when he actually arrives!”

The couple announced the pregnancy this fall while at the Emmys, where Benioff was nominated for 19 awards for Game of Thrones.
