Speaking exclusively to PEOPLE at the GQ Man of the Year party on Thursday, Nov. 14, the actor, 42, revealed that his son Malcolm Hiệp — who turns two on Nov. 24, 2021 — has settled well into his big brother duties following the arrival of his sister Méi June on Sept. 14. “He's doing good. He likes it. It's interesting, with our daughter, she's two months old so she doesn't do much,” the comedian tells PEOPLE about his family life with his wife Olivia Munn. “And I think the first couple of weeks he thought she might be a toy because she'd squeak and he'd be like, ‘How do I make it do that again?’ Now I think he gets it, that this is a little girl, yeah.” Speaking about his family's holiday traditions, Mulaney adds, “Let's see. Well, our son's birthday is right around Thanksgiving, so we always do kind of a combined with the family in town 'Malcolm birthday Thanksgiving,' so we'll do that again.” Never miss a story — sign up for PEOPLE's free daily newsletter to stay up-to-date on the best of what PEOPLE has to offer, from juicy celebrity news to compelling human interest stories.
