'Game of Thrones' stars Kit Harington and Rose Leslie are officially a couple

"Game of Thrones" co-stars Kit Harington and Rose Leslie are officially dating. They emerged as a couple on the red carpet of the Olivier Awards last Sunday.

The British couple showed up at the event at the Royal Opera House in London's Covent Garden holding hands and adoring. They even shared a kiss in between smiling to the camera.

In "Game of Thrones," Harington and Leslie play the roles of Jon Snow and Ygritte, who were a couple in the series. "Game of Thrones" fans should be ecstatic to know they took their on-screen romance behind the camera as well.

Over the weekend, Harington did not hold back in professing his love for Leslie during his appearance on "The Jonathan Ross Show."

"I fell in love in Iceland. I fell in love with my co-star," the fan-favorite "Game of Thrones" star told host Jonathan Ross with a smile.

"This is Rose who plays Ygritte who I've met who is just the loveliest girl and she could do so much better," Ross joked as he showed a photo of Harington and Leslie on the "Game of Thrones" set.

According to Vanity Fair, rumors about Harington and Leslie's on-and-off relationship started when "Game of Thrones" commenced.

When their "Game of Thrones" co-star Emilia Clarke was asked about the romance last January by Entertainment Tonight, here's what the actress had to say:

"My goodness! You know, we like to spread the love on our show. It's a beautiful thing. She's one of my best friends, so it's good. I mean, there are worse things than being caught kissing Jon Snow!"

Before they came out as a couple, there were already talks and mounting proof of the relationship between the "Game of Thrones" lovebirds.

The stars displayed some PDA as they shopped around Los Angeles, holding hands. They even shared a kiss and Leslie was at one point spotted resting her head on Harington's shoulder. And then, there's this:
