Adorable former co-stars Jason Momoa and Emilia Clarke were beaming when they reunited in London on Nov. 4, and the 31-year-old English actress took to Instagram to share a smiling snapshot of their fun night out. "When life is so good that your sun and stars is in your city," Clarke captioned the cute pic. "...You lose your eyes and gain 5 grins (and gins) where until now they'd only been one... (*grins- there's always more gins). @prideofgypsies YOU ALWAYS MOTHER OF DRAGONS MAIN MAN." Momoa, 38, was in London promoting the upcoming release of the hotly anticipated DC superhero team-up Justice League, in which he stars as the aquatic avenger, Aquaman.
