They grow up so fast.
Olivia Munn revealed that she and John Mulaney's 11-month-old son Malcolm has accomplished a huge milestone and has started talking.
"His first word was Daddy/Dada," the Predator actress, 42, captioned an Oct. 11 Instagram post of her baby boy twinning with his dad, "his second word was chó (Vietnamese for dog), and his third word is car."
In the clip, Malcolm recites the word "car" as he sits next to his father in matching khaki pants and a long sleeve black shirt. John acknowledged the father-son coordinating looks in Olivia's Instagram comments, writing, "Incredible outfit."
Olivia and the Saturday Night Live alum—whose relationship was made public in May 2021 following his split from wife Anna Marie Tendler—welcomed their son together in November 2021.
The following month, Malcolm made his Instagram debut just in time for the Christmas holiday.
"Meet Malcolm Hiệp Mulaney." the stand-up comedian captioned his Dec. 24 Instagram post. "He has his whole life ahead of him. He hasn't even tried seltzer yet. I'm very in love with him and his whole deal. Happy Holidays."
From then on, Olivia and John have been giving fans a peek into their family life with their newborn. Most recently, Malcolm crashed his dad's performance in Nashville, Tenn., in honor of the stand-up comedian's 40th birthday.
"Malcolm surprised John on stage last night to sing HBD with the whole audience," Olivia shared on her Instagram Stories Aug. 27, along with various photos of the touching moment. "And then he swiped some cake over John's shoulders."
John also commemorated the special moment, sharing an adorable photo of himself sitting on a stage covered in streamers and balloons while holding his son. He captioned the Aug. 27 Instagram post, "There is truly no better way to turn 40."
