Jason Momoa Goes Shirtless at His Birthday Party with Michael Fassbender!

Jason Momoa gives a thumbs up and sticks out his tongue while going shirtless at his birthday party on Sunday night (July 31) at Bull in a China Shop in London, England.

The former Game of Thrones actor, who turned 37 the next day, was joined by his buddy Michael Fassbender in the Instagram photo.

“@bullchinashope1 might need to rename the bull to. MOMOA in a chinashop Whisky starts flowing. The Clothes come off ALOHA kanaka,” Jason captioned the pic.

Jason posted a bunch of pics from the party, including one with wife Lisa Bonet.

In case you didn’t know, Michael used to be in a relationship with Lisa‘s daughter Zoe Kravitz, his co-star from X-Men: First Class.
