Jason Momoa is a tough man on screen as seen in his unforgettable portrayal of Game Of Thrones' fierce Dothraki King Khal Drogo. Now, he is all set to play the iconic superhero Aquaman.

On social media the actor has won the hearts of millions of fans with his ever smiling and charming personality. This time, for a change, it was his loving family that melted the hearts of his fans as the Aquaman star revealed how his wife Lisa Bonet and children gave him a surprise visit on the movie set on his birthday. The actor turned 38 on 1 August.

"I have never been so surprised in my life. 38 is the greatest to date," the actor wrote on Instagram as he shared an image of himself along with his wife and two children Lola Iolani Momoa and Nakoa-Wolf Manakauapo Namakaeha Momoa. In the image the actor can't seem to keep his eyes off his 49-year-old wife.

In the picture, the family is surrounded by a group of Hawaiian warriors dressed in native attire. "I love u my loveee my babies my friends and OHANA to my cast and crew. Mahalo for caring. It was so beautiful. Mahalos to all the warriors It was an honor," he added.

The 38-year-old Game Of Thrones actor met Bonet in 2005 and got married in November 2007 after having their first baby. Though the couple remain public shy, they never miss a chance to declare their love for one another on social media. Momoa often addresses his wife as the "moon of my life" and "partner in crime," on Instagram.

In June this year, the camera-shy actor urged the Australian press to respect his children's privacy while they were on a holiday. "Thank god for all my blessings Finally with my OHANA. Please please please. Australia Paparazzi Let me papa bear with my babies," he captioned an image where he was seen roaming along the sea line with his children.

Momoa will play the titular character in Aquaman and is currently filming for it in Australia. His performance in Batman vs Superman: The Dawn Of Justice may have been restricted to a blink-and-miss-it cameo, but he still had fans swooning. Now they are eagerly waiting to see more of him in the upcoming DC superhero film Justice League.

Aquaman is scheduled to release in 2018.
