Kit Harington surprises Fiancee with his severed head in the cruelest April Fool’s day prank and she lost It!

Imagine you’re at home, dressed in your comfy slacks, your guard is down, everything is fine, and you open your fridge only to find the severed head of your fiance’s  inside it. How would you react? Jon Snow may know nothing, but Kit Harington's got a trick or two up his sleeve.

The "Game of Thrones" star who appeared on "The Jonathan Ross Show" opened up about the April Fool’s Day prank that nearly cost him his relationship with fiancée and former co-star Rose Leslie.

"My family does April Fool's, her family doesn't do April no date," Harrington explained before host Ross rolled footage of Leslie opening her refrigerator to find a fake severed head staring back at her.

Upon discovering the head, Leslie set down the Brita filter she was holding and dropped to the ground in hysterics. Harington was nowhere to be seen as the prank unfolded, but managed to capture her hilarious reaction on camera.

It didn't go down well, he said.

She pretty much told me if I ever did it again that would be it, and I think that's marriage included.
