Jason Momoa got the surprise of his life on Thursday.

The actor expected to mark his 38th birthday on set in Australia with the rest of the Aquaman cast, but the moon of his life (wife, Lisa Bonet) had some other ideas. Bonet, 49, and the couple's two children, Lola, 10, and Nakoa-Wolf, 8, shocked the Game of Thrones star by traveling half-way around the world to celebrate with their leading man in person.

"I have never been so surprised in my life. 38 is the greatest to date," Momoa wrote alongside a photo of himself and his family surrounded by a group of Hawaiian warriors.

Momoa makes his debut as Aquaman in Justice League, which storms theaters on Nov. 17. His standalone film, Aquaman, is set for a 2018 premiere.
