The 31-year-old British actress, who plays Daenerys Targaryen on the HBO series Game of Thrones, spent time with Momoa, who portrayed Daenery's husband, Khal Drogo, in Season 1, Sunday in London.
"When life is so good that your sun and stars is in your city...you lose your eyes and gain 5 grins (and gins) where until now they'd only been one... (*grins- there's always more gins)," Clarke captioned a photo with Momoa, using Daenerys' pet name for Drogo.
