Emilia Clarke Reveals 'Game of Thrones' Sex Scene Trick

We've heard about the "modesty sock" used in Hollywood sex scenes, but the pink and fluffy sock? That's a new one.

Game of Thrones favorite Emilia Clarke—who reigns as mother of dragons Daenerys Targaryen on the hit HBO show—shared a behind-the-scenes secret while visiting The Graham Norton Show on June 19. The actress had to film some very dark and often violent sex scenes during Season 1 when her character belonged to Dothraki warlord Khal Drago, played by Jason Momoa—and it was Momoa's sense of humor that got them through it.

"He decided for one of the scenes, which was on his back and my face, he decided not to use a modesty sock, but to use a beautiful, pink fluffy sock," she says. "So getting that close-up from me looking petrified and just like I didn't want it to happen, was just lots of laughter— 'It's huge, and it's big, and I don't know what to do with it!'"

The star was joined by Cara Delevingne, Jake Gyllenhaal, and her co-star in the upcoming Terminator: Genisys, Arnold Schwarzenegger, who all got a big laugh from the image of Momoa's intimidatingly brute Drago donning anything pink or fluffy.

"He doesn't look like a funny man," pressed host Graham Norton.

"A little bit of whiskey, and he's very funny," she joked.
