They may enjoy pranking each other every so often, but it’s pretty clear that Hugh Jackman and Ryan Reynolds are very close, so much so that they may even be … related?

On Saturday, April 6, the Wolverine actor, 50, took to Instagram to share a great throwback photo of he and the Deadpool star, 42, The picture shows both men as kids way before they hit it big in Hollywood. “Brother?” Hugh captioned the black and white pic. Take a look at it below!

Fans were of course loving the photo, as some took to the comments section to react. “Lmao you two are too much,” one said. “Is this before you got superpowers and hated each other,” another joke, while one user responded with, “HAHA I love them.” But the Canadian actor of course chimed in after seeing the photo, taking it to Twitter to respond.

“I had no idea you were such a gorgeous kid. Oh, that’s me,” Ryan said.

Ryan wasn’t done joking, as he also decided to respond on Instagram, stating, “Mom’s frequent trips to Australia suddenly explained.” The pair have poked fun at each other for quite some time now. Over the holidays, Hugh and fellow actor Jake Gyllenhaal teamed up to pull a big-time Christmas prank on The Proposal costar. It seems like Ryan showed up to a party wearing an ugly sweater after being told by his two acting buddies that that was the theme. It was not.

“These f–king a–holes,” the father-of-two captioned a pic showing Jake and Hugh exchanging a high-five while Ryan stands between them. As if it couldn’t get worse for Ryan, his own wife, Blake Lively, gave the post an Instagram like.

They may be quite famous and busy, but it’s certainly nice to see these two pals having a good time while harmlessly joking with each other.
