'Game of Thrones': Rare King Joffrey Sighting ... Bow And Watch Me Vogue!!!

EXCLUSIVE

Jack Gleeson -- aka King Joffrey from "Game of Thrones" -- resurfaced far beyond The Wall, at a cosplay conference in Abu Dhabi, acting like a shell of his former 'GoT' character.

No heads on spikes here ... just some good old fashioned Madonna-like "Vogue" and robot dance moves while Jack cut loose backstage with hot gamer chick Naomi Kyle.

In case you're out of the loop ... Jack quit TV and film acting after his 'GoT' run to start his own theater company with his buddies ... so we're calling this a rare sighting.
