I mean really, if you're going to throw Jason Momoa a 40th birthday party, you should do it in Des Moines. Oh well. His friends got together and threw him a surprise party. His wife was missing for some reason. But, the takeaway from the party is he's so NOT Hollywood. There were some famous faces at the party, but everyone seemed so down to Earth. The caked was representative of his life and made of whiskey and Guiness! Quite a site! Take a look inside the party. Some of the language is NSFW, so be warned.
