It was not a lazy Sunday for Amanda Peet! Yesterday, the actress gave birth to her third child, a son, with her Game of Thrones creator husband, David Benioff, People reports.

The couple revealed that the new arrival's name is Henry Peet Friedman; the baby boy joins daughters Frances, 7, and Molly, 4, in the family. Peet confirmed her pregnancy at this year's Emmy Awards and in October she told People that the girls were "very excited" about the arrival of their younger brother. Next in store for the mom of three? Peet is starring in the new HBO series Togetherness, which is set to debut in 2015.
