Sophie Turner and Joe Jonas hit up Comic-Con!

The Game of Thrones star and her boyfriend made their way to San Diego, California for the annual comic-book event on Friday. ET's Leanne Aguilera chatted with the 21-year-old actress at the convention, where she gushed about Jonas and that surprising Ed Sheeran cameo.

"He's a good accessory," Turner joked when asked about taking Jonas to the GOT premiere last week. So is DNCE frontman rooting for Turner's character, Sansa Stark, to end up on the iron throne?

"I don't know, I don't know," she replied. "We don't talk about it... You made me blush! Oh god, yeah! I'm sweaty, I can't tell."

While the red-haired actress seemed shy talking about Jonas, Turner did say she's "smitten" with "wife" Maisie Williams, who was so excited to have Ed Sheeran guest star on GOT.

"That was fun because Maisie loves Ed Sheeran and [creators] David [Benioff] and Dan [Weiss] had it as, like, a surprise for her," Turner shared. "So they just, they didn't tell her. I told her by accident! I was like, 'Oh, when's Ed Sheeran coming on the show?' But yeah, they kind of did it as a surprise. I was kind of mad because I've been talking about [Justin] Bieber coming on the show for a while now. But it's fine, I'm over it."

The "Shape of You" singer appeared in the season seven premiere and unexpectedly received harsh criticism from the show's fans.

"I thought he killed it," Turner said of his performance. "Ed Sheeran is a hero! No one slay Ed Sheeran! That's rude."

The hit HBO series comes to an end next year, so can fans expect a happy ending for Williams' Arya and Turner's Sansa?

"I think we have more chance in the Marvel universe than Game of Thrones, cause were not about happy endings on Game of Thrones," Turner said.
