Balfe and McGill have managed to keep their relationship out of the spotlight and unfortunately, very little is known about the couple.
In a 2018 interview with Parade, Balfe addressed the Outlander fans who wanted Heughan and her to be together in real life.
She said: “There’s a small vocal group that really wanted it, which is just a testament to the characters that we portray, that the love story is so inspiring and so aspirational that people just really wanted to believe in it.
“And that’s a nice thing. But I think things are pretty clear now that I’m engaged to someone else. Everyone gets it now.”
Outlander season 1 to 5 are streaming on Starz and Amazon Prime now
