Kit Harington and Rose Leslie, best known for playing the role of Jon Snow and his Wildling lover Ygritte on the hit HBO show Game of Thrones, made their red carpet debut as a couple at the Olivier Awards in London on Sunday.

Harington donned a black tux and Leslie looked stunning in a Malene Oddershede Bach gold dress as they walked the red carpet, gazing into each other eyes and sharing a quick kiss for the shutterbugs.

Harington, 29, and Leslie, 29, were first spotted together in 2012, sparking rumors of a romance. However, the two reportedly called it quits later that year. However, the couple apparently rekindled their romance in 2014 and were seen together during a shopping trip to Los Angeles earlier this year.

In spite of being pictured together, the two kept mum about their relationship, but their friend and Game of Thrones co-star Emilia Clarke kind of hinted that they were in a relationship in January. 

"My goodness! You know, we like to spread the love on our show. It's a beautiful thing," Clarke said at the time. "I mean, there are worse things than being caught kissing Jon Snow!"

While Leslie's last appearance on the fantasy-drama was in Season 4, the fate of Jon Snow hangs in the balance amid rumors of the fan-favorite character's return to the show after being killed off last season.

However, the actor revealed on Saturday night that he will not be making a comeback on the show.

"I am no longer involved in the show so any secrets that are with the show I don't actually know anymore," Harington told Jonathon Ross. "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 realise that I don't come back."
