To some, true love is when your heart skips a beat every time you're with a special someone, or when you can tell what they're thinking just by looking into their soul, but to others... well, it's when you know you can scare the absolute sh*t out of them and still share the same bed at the end of the day.
Enter Kit Harrington and Rose Leslie, or AKA Jon Snow and Ygritte.
While appearing on The Jonathan Ross Show, Kit revealed that he once put a fake severed head of himself in the fridge to trick Rose on April Fools Day... which, to be fair, is rather elementary compared to what they're used to from Game of Thrones.
Although, unfortunately for poor Snow, things didn't go according to the no-harm-done plan.
"My family does April Fools... her family doesn't do April Fools..." he laughed.
"After that, she was in tears and I was there like... 'April Fools...!'
"It didn't go down well.
"She pretty much told me that if I did it ever again then that would be it and I think that's marriage included."

Now, let's just watch that reaction one more time...
Like we said... true love <3
