Ryan Reynolds has finally revealed the name of his and Blake Lively’s fourth child while thanking his family at Monday’s world premiere of “Deadpool & Wolverine” in New York City.

Footage making the rounds from the Lincoln Center event shows the 47-year-old “If” star giving his family a touching shoutout, nearly a year and a half after he and the “Gossip Girl” star, 36, welcomed their latest addition.

“I just want to say that there are so many people who have loved this film into this exact moment and I am so eternally grateful to those people, many of whom are in this room or standing here on the stage, one of whom is not. So I just want to start by saying thank you to my wife, Blake, who’s here,” said Reynolds in an introduction to the film, which also stars Hugh Jackman.

“I want to thank my kids — James, Inez, Betty, Olin — who are here. I hope, you know, if I’m lucky, this moment will be the most traumatic thing, considering the contents of this movie, that happens in your wondrous life. I love that my entire family is here.”

The couple, who met on the set of 2011’s widely panned “Green Lantern” and wed two years later, have yet to publicly share the sex of their fourth child.

To date, little Olin is the only member of the Reynolds-Lively clan who has yet to inspire a Taylor Swift song. The Grammy winner, 34, who is a close friend of the actors, notably nodded to their three elder daughters — James, 9, Inez, 7, and Betty, 4 — in the track, “betty,” off 2020’s “folklore.”

Reynolds on Monday suggested to E! News that he and Lively’s brood could always use more members.

“The more the merrier,” he joked to the outlet. “As many as possible. As many little heartbeats as possible, just running around, wrecking stuff in the house. I love it. Let’s have more!”

Reynolds during the pre-show remarks also paid tribute to late Marvel art director and production designer Ray Chan, who died on the last day of filming. He was 56.

“If we were lucky enough … he’d be standing up here today with us. He’s an artist, he’s an incredible person. His legacy lives on and is on the screen up here,” said Reynolds. “This movie is genuinely and wholeheartedly for Ray.”
