Sophie Turner -- aka Sansa Stark from " Game of Thrones " -- has still got a thing for ex-hubby Tyrion Lannister, or maybe even Peter Dinklage .

Sophie was at a 'GOT' party at Comic-Con when she saw some random dude in a Tyrion mask ... a very good one we might add. The spirit moved her to straddling the guy and sticking her tongue down his mask.
