The 28-year-old singer is a "big nerd" when it comes to the HBO fantasy drama series so he's quite relieved his fiancee - who plays Sansa Stark - won't let him look at her scripts or drop any hints about what's in store in the upcoming final season of the show.

Asked if he gets let in on any secrets, he told hit105's Stav, Abby and Matt: "I wish I could say anything but the truth is, she doesn't give me spoilers.

"So I kind of respect it because I'm a fan of the show and I'm a big nerd at heart, so if I was told how things were gonna turn out, I probably would have been disappointed because we have to wait so long for the next season."

But the DNCE star isn't the only one kept in the dark by their cast member partners.

Rose Leslie, who previously played wildling Ygritte, recently admitted she banishes her fiance, Kit Harington - who is known to fans as Jon Snow - from their home when he gets new scripts through because she's so determined not to find out what happens in the final set of episodes.

She said recently: "I'm like the rest of the world. I'm waiting for the new and final season.

"I remember over the summer obviously the new episodes for the final season were coming through onto his iPad. I can read his facial expressions. I don't want to know anything that's going on within his eyes, so I sent him packing.

"I kind of boot him out so that he can go to the coffee shop, because I can gauge. If he stiffens, it's like, 'Ooo someone's dead.' And then my mind goes off."

The final season of 'Game of Thrones' is scheduled to air in 2019.
