Spotted: Ryan Reynolds and Blake Lively‘s son wreaking a little havoc. 

The Deadpool star revealed that he and the Gossip Girl alum’s 2-year-old son Olin has been quite the challenge to parent compared to their three daughters: James, 10, Inez, 9, and Betty, 6. 

“Three girls—just so easy,” Ryan quipped during an Oct. 9 appearance on Late Night With Seth Meyers. “And then the boy, who’s gotta break everything.” 

He continued, “I’m, like, in direct competition with this young man.”

In fact, the Free Guy actor hilariously confessed that he might not have been open to adding a fourth addition to his family had circumstances been different. 

“If I had, like, three boys at first,” Ryan said, “I would never. There’s no way. I would give myself a punching vasectomy. There’s no way I would allow that to happen.”

Indeed, the 48-year-old has previously gotten candid about how much he loves being a girl dad.
