During the New York City premiere of Deadpool & Wolverine, Ryan Reynolds revealed the name of his youngest child whom he shares with Blake Lively.

“I want to start by saying thank you to my wife, Blake, who is here,” he told the crowd. “I want to thank my kids James, Inez, Betty, Olin, who are here. I hope that, if I’m lucky, this moment will be the most traumatic thing — that is, the contents of this movie — that happens in your wondrous life.”

“I love that my entire family is here.”

Reynolds, 47, and Lively, 36, are parents to daughters James, 9, Inez, 7, and Betty, 4. Last February, the couple welcomed their fourth child just five months after it was confirmed the Gossip Girl alum was pregnant.

“We’re very excited. Look, we wouldn’t do this four times if we didn’t love it,” Reynolds said during a February 13, 2023 appearance CNBC’s Power Lunch.

“Everybody’s doing great. Everybody’s actually doing fantastic. If we hadn’t figured it out by now, I think we’d be in deep, deep trouble.”

At the time Reynolds didn’t disclose their child’s name or the sex of their baby.

The Deadpool actor said the couple had a habit of waiting to learn about the sex of their baby until they were born.

“We never find out until (the baby is born),” he told Today. “I know girls. So, I”m kind of hoping (for that), but I’m ready for whatever happens.”

Congratulations Blake and Ryan! And welcome to the world little Olin!
