Ryan Reynolds & Blake Lively Finally Announce the Name of Baby No. 4

More than a year after Ryan Reynolds and Blake Lively added their fourth child to the family, they're finally sharing the name they chose. While promoting his upcoming movie Deadpool & Wolverine in New York City on Monday, Ryan thanked each of his family members for their support by name — and yes, that included their newest addition, who was born in early 2023. Looks like they weren't waiting for Taylor Swift to include the name in a song after all!

Ryan spilled the beans while on stage.

When Ryan joined his costars on stage at the NYC premiere of the movie, not only did he compliment Blake's outfit, but he also thanked each of his children for being there by name. That includes James, 9, Inez, 7, Betty, 4, and Olin, who was born in February 2023.

"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," he said.

He didn't share anything new about Olin beyond the name.

In fact, at this point, we don't even know if Blake and Ryan's fourth baby is a boy or a girl — but it's still cool that we now know what their little one is called after more than a year of speculating.

"I love that my entire family is here," Ryan said during his speech.

Blake and Ryan's famous friend revealed the name of their second youngest child, Betty.

When Taylor Swift surprised fans by dropping her album, Folklore, in the summer of 2020, listeners quickly realized that Blake and Ryan's oldest daughters, James and Inez, were mentioned in a song called "Betty." The theory was later confirmed to be true, so of course, fans were wondering if the same thing would happen this time around.

Ryan recently joked about Taylor naming their children.

When Ryan was asked if Taylor would be doing the reveal again this time around during his interview on the Today show in May, he joked that he was waiting on her to put a song together, calling her a "prolific writer."

"We always wait for Taylor to tell us what the child’s name will be," he said.

We can't wait to learn more about Olin!

Now that this baby's name is out there, maybe Ryan and Blake will share more about Olin like they do when they drop fun stories and details about their three big kids.

In the meantime, we hope Taylor's busy writing that song. She can't leave Olin out!
