Seyfried gave birth to her first child, a baby girl, in March after getting secretly married to the Life in Pieces star. Earlier that month, ET spoke with the couple at the premiere of their film, The Last Word. "I'm ready," Seyfried said of becoming a mom.

"I'm blown away by her every day," Sadoski gushed over his wife. "That's the great joy for me, trying to learn as much as I can -- try to stay out of the way and not screw anything up too much."
