The "Saturday Night Live" standout, 34, and his wife, Maggie Carey, welcomed their second daughter, Harper, in New York on July 28, his rep confirms to Us Weekly. Married since 2006, Hader and his writer-director spouse are already parents to Hannah Kathryn, who will turn 3 on Oct. 6.
During an appearance on "Late Night With Jimmy Fallon" in 2010, Hader joked about some of the more humorous aspects of raising a newborn. "When [Hannah Kathryn] poops herself, that's the funniest thing because she just gets, like, a total blank look on her face and fazes out," he laughed. "It's the loudest noise."
Hader was recently nominated for a Primetime Emmy Award in the Outstanding Supporting Actor in a Comedy Series category. He's up against "New Girl" actor Max Greenfield, 31, and "Modern Family" stars Ed O'Neill, 66, Eric Stonestreet, 40, Jesse Tyler Ferguson, 36, and Ty Burrell, 44.
"It's a great honor, though there should be parentheses next to my name with all of the SNL writers," Hader told Us in a statement. "And now I have to kiss up to the cast members of Modern Family in hopes that they pull a Ving Rhames and give me their award when they win."
In addition to "Saturday Night Live," Hader's film credits include "Superbad," "Forgetting Sarah Marshall," "Tropic Thunder," "Knocked Up," "Adventureland," "Cloudy With a Chance of Meatballs," "Pineapple Express" and "Night at the Museum: Battle of the Smithsonian."
