Sophie Turner on Who Knows How 'Game of Thrones' Ends

“Extra” was with Sophie Turner and her “Dark Phoenix” co-star Tye Sheridan at WonderCon, where she dished on the end of "Game of Thrones," hanging with her fiancé Joe Jonas and his brothers, and her upcoming wedding.

As for her nuptials, she dished, “Wedding planners are key — that means you don't have to do anything.”

Turner was spotted with Joe, Kevin and Danielle Jonas, and Nick and Priyanka Chopra in Miami earlier this week, leading many to speculate they are working on another video together. Sophie would only say, “Miami was fun, I'm really sunburned. It was a lot of fun!"

Her co-star Tye hadn't gotten the memo that she was featured in the new video for “Sucker.” Tye asked, "You're in a music video?" to which Sophie replied, “I'm in the new Jonas Brothers video." When Tye said, “No way!” Sophie replied, “Yeah, it was really fun.”

Turner's mega-hit show “Game of Thrones” is about to premiere its final season, and she revealed who, in her life, knows how it ends: "Two people — my fiancé and my publicist.”

Sophie admitted to "Extra" she is nervous for her new X-Men movie “Dark Phoenix” to come out, saying, “I get anxious before anything comes out, so I just try to sleep as much as possible and stay calm.”

The cast gave fans a sneak peek of scenes from the X-Men adventure at the convention. Turner said, “To like go out there and show them some of what we've done and see their reaction in person, it's really exciting.”
