"It's a great feeling," Nick said. "I mean, it's kind of a dream where, as close as we are as brothers, that our wives and fiance are so connected as well."
The "Chains" singer admitted that reforming the Jonas Brothers band was "obviously a huge adjustment for everybody," but they've gotten nothing but love and support from their significant others, including Kevin Jonas' wife, Danielle.
"These incredible women have handled it so well and have been the best support system for each of us, individually and as a group," Nick shared. "To get to share that with them is a really amazing thing."
While Priyanka has been welcomed into Nick's close-knit family, the 26-year-old entertainer said that he's managed to blend in well with his wife's family as well, and that their close connections to their loved ones is something that really connected them as a couple.
"It is one of the things we were so drawn to about each other," Nick explained. "And the family's just getting bigger and bigger, and that's a beautiful thing."
"We love including our loved ones, our family, in everything we do… our house is for everyone, our doors are always open," he added. "That is, in my opinion, how it should be."
His latest film, UglyDolls -- based on the toy line of the same name -- is also something everyone in his family can enjoy, even if some of the younger members of his family don't totally understand how he's involved.
"Priyanka's niece was there, and she was trying to explain to her, she's like, 'You know, that's Uncle Nick's voice,' And she didn't get it," Nick recalled. "She's very young, [and] she was like, 'What do you mean it's his voice? That's Lou. It's just the guy in the movie.' So I'm not sure I'll be able to explain to them until they're a little bit older that's it me doing the voice."
"It's kind of like ruining Santa Claus, so I don't want to do that," Nick added.
"I was explaining to her, because she was confused, and I said, 'It's my voice. Like, you know, like how Elsa and Anna, there's a person that plays Elsa and Anna?' And I didn't get what I was doing!" Clarkson shared. "I saw her little face, and I just saw the wheels spinning, and it was like, 'Oh no!'" Check out the video below to hear more.
