'Game of Thrones' lovebirds Kit Harington, Rose Leslie finally engaged

After denying engagement rumours earlier this year, Game of Thrones' onscreen — and offscreen — darlings Kit Harington and Rose Leslie finally announced their engagement late Wednesday night, according to a British media outlet reported.

Harington — who plays Jon Snow in HBO's hit fantasy drama TV series — met Leslie in 2011 while filming the show's second season in Iceland, BBC reported.

The British duo — both 30 — only had a brief on-screen romance before Ygritte, Leslie’s character, died in the arms of Snow in the Emmy-winning show's season four.

"You know nothing, Jon Snow” — Ygritte's final words — became one of the series' most famous lines.

Following Ygritte's shocking death, rumours surfaced that the two were dating and merely strengthened after the couple made its first public appearance together at the red carpet of the Olivier Awards back in 2016.

“If you’re already attracted to someone, and then they play your love interest in the show, it becomes very easy to fall in love,” Harington told Vogue magazine in an interview last year.

"Because the country is beautiful, because the Northern Lights are magical, and because it was there that I fell in love," he said.

Harington termed the time he filmed Game of Thrones Season 2 as the most memorable moments of the show.

Jon Snow does know something after all!
