The stars met on set in 2011 while shooting in Iceland, and though their steamy love affair did not end well in Westeros, all heartbreak was healed when the duo tied the knot in Scotland in 2018.
But their romance hasn't been picture perfect — from a stint in rehab to an alleged cheating scandal, Radar has all the details of these Game of Thrones stars' relationship history.
Harington met Leslie while filming season 2 of GoT. Later, Harington reminisced on the origins of their love story to Vogue Italia 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.”
Dating rumors swirled when the couple was spotted holding hands in London.
A year later the couple quietly split. They were still so under the radar as a couple barely any reports of their romance (and why it ended) exist.
It wasn't until August 2014 Us Weekly broke the news that Harington and Leslie had rekindled their romance three months earlier in May of 2014.
Though Harington and Leslie had been romantically linked for several years, it wasn't until the 2016 Oliver Awards in London that Harington and Leslie made their red carpet debut as a couple.
The couple's engagement was confirmed via a traditional announcement in The Times. Harington admitted that thanks to red wine and a roaring fire he popped the question spontaneously, instead of following his original proposal plans. He claimed to have botched the moment but she still said yes.
Harington and Leslie wed in Scotland at Kirkton of Rayne church on June 23, 2018, followed by a reception at Leslie's family estate.
The first real scandal emerged when Russian model Olga Vlaslova alleged she and Harington met in Luxembourg, and subsequently began an affair — a tryst that she claimed carried on after his marriage to Leslie. Harington not only denied knowing the model and ever having any kind of relationship with her, he also stated he'd never even been to Luxembourg.
Harington hosted SNL, Leslie surprised him during his opening monologue in which she hilariously drilled him about what they are going to do for money now that GoT was coming to an end. The couple also exchanged onair "I love yous."
Weeks before the series finale of GoT, Harington checked into rehab for alcohol and stress. Reports circulated that although facing the end of the series caused Harington distress, wife Leslie remained "extremely supportive" — and she in fact was the driving force behind him seeking professional help.
Unconfirmed reports circulated that Harington and Leslie were headed for divorce — a statement from Harington's rep firmly denied the rumors.
Still going strong, the duo stepped out on the red carpet at the 2020 Golden Globes — Harington was nominated for best Actor in TV Series Drama.
