Kit Harington and Rose Leslie make red carpet debut as couple

LONDON, April 4 (UPI) -- Former Game of Thrones stars Kit Harington and Rose Leslie made their red carpet debut as couple Sunday.

The 29-year-old English actor and 29-year-old Scottish actress attended the 2016 Olivier Awards at the Royal Opera House in London.

Harington and Leslie were casually affectionate on the red carpet, sharing a quick kiss for the cameras. The actor wore a requisite black tuxedo, while Leslie stunned in a gold Oddershede Bach gown.

The former co-stars first sparked dating rumors in 2012 and appeared to rekindle their relationship in January. They were spotted holding hands on a shopping trip and were later seen with Game of Thrones star Sophie Turner at LAX.

"Kit is a lovely and funny man, and a dear friend," Leslie told People magazine in 2014. "It was always such a privilege to be working opposite him and such a blessing that we get on in real life because it made our characters more believable."

Harington and Leslie played ill-fated lovers Jon Snow and Ygritte on Game of Thrones. Ygritte was killed off in Season 4, while Harington remains adamant Jon Snow is dead after appearing to die on the Season 5 finale.

"I am no longer involved in the show," the actor said on Saturday's episode of The Jonathan Ross Show. "You're looking at me like you don't believe me. It's going to be so relieving when people actually see the show and realize that I don't come back."

"I was playing a corpse," he said of his recent appearance on set. "I won't tell you how many episodes I'm lying dead but it's enough that I was out there for quite a while. It's going to be so satisfying when you see it and you realize that I was telling the truth the whole time."

Harington will next star in Brimstone with Game of Thrones actress Carice van Houten and is also slated for The Life and Death of John F. Donovan with Jessica Chastain. Leslie will appear in Morgan with Kate Mara and Sticky Notes with Ray Liotta.
