"For years, we tried to get Ed Sheeran on the show to surprise Maisie, and this year we finally did it," Benioff said with a nod to Williams who is a known fan of Sheeran's.

They didn't give away any details on the nature of Sheeran's appearance but according to Variety, HBO has confirmed the guest-spot.

However, all they said about it was: "He has a role. No more details".

In an effort to move away from the subject at the panel, Turner joked: "I'm still waiting on [Justin] Bieber", to which Weiss replied jokingly: "You're waiting on Biebs? Season nine."

Game of Thrones was recently announced to be returning to screens on July 17.
