Joe Jonas Had To Sign NDA Over 'Game Of Thrones'

Game of Thrones star Sophie Turner says her fiancé, Joe Jonas, signed a non-disclosure agreement with HBO.

The 23-year-old British actress, who plays Sansa Stark in the show, said during Tuesday’s episode of Good Morning America that Jonas figured out how the series ends after visiting her on set. She told hosts Amy Robach and Michael Strahan:

"He was on set for most of it, so he kind of figured it out and then he had to sign an NDA. … He had to have full photo approval on set, his camera was covered up – everything. … He’s terrible at keeping secrets .... "Yeah, you can give him a call. He’ll probably tell you everything."

Jonas and Turner began dating in late 2016 and announced their engagement in October 2017.

The final season of Game of Thrones premieres on HBO on April 14th.
