Things may not have worked out between Jason Momoa and his "love of my life", Lisa Bonet, but Momoa's heart is still as warm as the sun.

He turns 43 today, on August 1, 1979, and his idea of celebrating his special day is to do something good for a brother.

In a very worlds-collide moment, Momoa recently posted a picture of him and Josh Brolin together, writing, "I love this man with all my soul. truly my older brother.”

Brolin also waxed eloquent about him, calling him a “saint” and not of “human stock” and fans thrilled at DC meets MCU.

Later, he also posted a picture of him and Ben Affleck looking rather chummy, thereby announcing Batman’s return, as Affleck, in the DC universe.

Fans were excited about Ben Affleck coming back as Batman, even as some bemoaned the loss of Henry Cavill as Superman.

But it’s Momoa’s birthday wish that showed fans the largesse of his hearts.

He wants fans to sign up for bone marry donation, as a birthday gift to him, to help his leukemia-stricken friend, Travis Snyder.

Happy Birthday Jason Momoa, may you get all your wishes on this 43rd trip around the sun!
