See Sweet Photos of Jason Momoa "Spreading Aloha" During a Recent Children's Hospital Visit

As if there were ever any doubt, dad of two Jason Momoa is a real-life superhero. Just a few weeks after wearing a tank top to the Golden Globes, the actor did something even more amazing by visiting patients at the UPMC Children's Hospital of Pittsburgh during his free time while filming upcoming thriller Sweet Girl in the city. "The greatest part of being Aquaman is making children happy," he wrote on Instagram, adding, "Met so many brave strong babies all my aloha to the families."

In one of the videos in the album he shared to Instagram, Jason arm wrestles one kid, Joshua, for a visit to the set of the Aquaman sequel. "If you win, you're coming. If I win, you're still coming," Jason tells him in the video. When Joshua does indeed win, Jason refers to his famously muscular arms and says, "These are fake." See all the heartwarming shots from Jason's visit above.
