Sophie Turner Told Fiance Joe Jonas How ‘Game of Thrones’ Ends – But He Had to Sign an NDA (Video)

And apparently he’s “terrible” at keeping secrets, so

If the “Game of Thrones” ending slips before the HBO series comes to an end this May — or before its final season even premieres in less than two weeks — there’s a small chance the leak came via Joe Jonas. This is because “GoT” star Sophie Turner admits she told Jonas, her fiance, how the David Benioff and D.B. Weiss-created show ends and because he’s a “terrible” secret-keeper.

“I have. Well, actually, he was on set for most of it, so he kind of figured it out and then he had to sign an NDA,” Turner told “Good Morning America” hosts Michael Strahan and Amy Robach, during a sitdown with her and co-star Maisie Williams on Tuesday.

Yes, knowing the end of one of the most popular shows in TV history apparently comes with the price of signing a legal agreement that you will not reveal said ending — even if you are marrying Sansa Stark.

“He had to have, like, full photo approval on set, his camera was covered up. Everything,” Turner added.

But perhaps there is a chance that non-disclosure agreement may not be enough to keep Jonas quite, as the actress says her soon-to-be spouse has some loose lips.

“Yeah, you can give him a call. He’ll probably tell you everything,” she said, joking — we think.

“Game of Thrones” Season 8 premieres April 14 at 9/8c on HBO.
