Joe Jonas revealed Sophie Turner’s hilarious condition at the start of their relationship on Monday’s The Late Late Show with James Corden.

‘Sophie, she said, ‘Look, if we’re going to get married’ and it was actually, ‘If you’re going to date me, you have to watch the Harry Potters,” the 30-year-old hitmaker joked of his wife’s request.

He added: ‘Because every Christmas, for those of you that are watching that don’t know, every Christmas in the U.K. they just stream and play Harry Potter, all of them.’

After admitting he ‘fell in love’ with the hit franchise, based on J. K. Rowling’s seven novels, Jonas insisted his wife binge-watch the Lord of the Rings under California’s coronavirus lockdown.

During their viewing experience, he told Corden they’ve built ‘plenty of Legos,’ which correspond to some of their favorite fantasy adventure films and shows. 

‘We’ve done three Lord of the Rings Legos, we’ve done Hogwarts, the castle, which is like 7,000 pieces, the Batmobile, and Stranger Things. So we’re running out of options at this point,’ he confessed.

According to Jonas, Turner is ‘the talented one when it comes to Legos.’ 

The lovebirds, who are reportedly expecting their first child, first sparked dating rumors when they attended a Kings of Leon concert together in late 2016.  

Sophie and Joe have been together since late 2016; the pair met through mutual friends and kicked things off by DMing each other.

One year after their first date, they were engaged.

Sophie later told Harper’s Bazaar: ‘We had a lot of mutual friends and they’d been trying to introduce us for a long time. 

‘We were following each other on Instagram and he direct-messaged me one fine day, out of the blue.’

Rumors that they were an item first swirled when they were seen cozing up at the MTV EMAs in November 2016, pictured on several occasions afterwards at various other events.

The pair then made it ‘Insta-official’ in January 2017, when Sophie shared a snap of Joe smoking a cigar on a boat in Miami.

When questioned at the Golden Globes about it by Extra TV host Mario Lopez, Sophie just said: ‘I’m not saying anything… I’m very happy.’

They were seen in March 2017 for Paris Fashion Week, holding hands, and then Sophie spoke about Joe in a chat with Marie Claire, discussing what it’s like to be in a celebrity coupling.

They became engaged shortly after, in October 2017, with Sophie saying in an interview afterwards: ‘It’s lovely to be engaged.

‘Not like I achieved anything, but I found my person, like I’d find a house that I love and want to stay in forever,’ she gushed. ‘There’s a sense of peace that comes with finding your person.’

She told Rolling Stone in March 2019: ‘I was fully preparing myself to be single for the rest of my life. I think once you’ve found the right person, you just know.’

‘I feel like I’m much older a soul than I am in age. I feel like I’ve lived enough life to know. I’ve met enough guys to know – I’ve met enough girls to know. I don’t feel 22. I feel like 27, 28,’ she concluded.

Ahead of their first anniversary, Jonas told Corden he might recreate the Sin City bash at home. 

‘We legally got married in Vegas, so it’s our Vegas anniversary,’ the Grammy nominee said of their first anniversary coming up on Friday, before adding that the couple probably ‘would have gone back to Vegas’.

He continued, ‘So, if you can keep a secret, I would say I might try to recreate Vegas in our house.’

Corden joked that the couple could have a Zoom call with the Elvis impersonator that officiated their wedding, to which Joe quipped that he would have to make him sign an N.D.A this time after he leaked information about the duo’s ceremony to the press last year.
