Game of Thrones co-stars Kit Harington and Rose Leslie make their red carpet debut as a couple

THEIR romance has been on-again, off-again for a few years, but Kit Harington and Rose Leslie have now made it official on the red carpet.

KIT Harington and Rose Leslie have made their big public debut as couple.

The Game of Thrones actors stepped out hand-in-hand at the Olivier Awards in London on Sunday, finally making their relationship red carpet official — you don’t get more official than that.

The glamorous pair were clearly smitten with each other as they exchanged smiling glances and giggles in front of the cameras in their first major public appearance as partners.

Harington plays Jon Snow, who was in an on-screen fiery relationship with Ygritte, Leslie’s character. In real life, the British actors have been in an on-again, off-again romance for a few years.

Harington cheekily professed back in March last year that “redheads” were his weakness when it came to women while the two were broken off.

Earlier this year perezhilton.com reported they were spotted acting “very couply” together in Soho, London, with Rose ruffling her hands through Kit’s hair.

So finally, the pair have decided to show the world they have patched things up and let their love be officially known.

And the timing couldn’t be better for already-excited fans awaiting the return of the popular HBO fantasy drama for its sixth season on April 25 (AEST) — when we will at last know once and for all the fate of Jon Snow.
