Olivia Munn's mom got the last laugh when she first met comedian John Mulaney.

During an appearance on Late Night with Seth Meyers on Monday (May 12), Munn shared the memorable way her now-husband met her mom, Kim, for the first time shortly after they welcomed their first child together, son Malcolm, in 2021, per Page Six.

"So Malcolm was born the day before Thanksgiving and my mom comes, first of all, has never met John by this point," she said, adding that her mom showed up to the house and "doesn't even say hi to John" before she "unzips her suitcase [and] takes out frozen turkeys."

The Newsroom actress explained that her mom often tells lies and stories because "she just can't help herself," and so she did the same with Mulaney, convincing him of a family tradition where babies pose with turkey legs on Thanksgiving.

"She says to John, 'You know, it's so exciting, in my family with all of our kids, the tradition [is] we put a drumstick in their hand for their first Thanksgiving when they're a baby.'"

Munn said she was confused when Mulaney relayed the plan to her as "that's not a tradition," and she even called her siblings to see if they knew what their mom was talking about.

"They said, 'No, because she's lying,'" she recalled.

Despite this, Kim stuck to the plan and placed baby Malcolm in his dad's arms before giving the newborn a drumstick to hold and taking a photo. Munn added that her mom then pat the comedian's hand and said, 'OK, a new tradition.'"

Host Seth Meyers noted that "it's such a good lie" because "nothing is gained from it at all" other than now having a hilarious photo of their baby.

In addition to Malcolm, Munn and Mulaney are parents to daughter Méi, whom they welcomed via surrogate in 2024, months after they tied the knot in a small wedding ceremony.
