Nick Jonas On Kevin's Wife, Danielle: 'It's Kind Of Hard To Believe I've Got A Sister-In-Law'

The Jonas Brothers were bound to be infiltrated by some estrogen sooner or later. And we’re not talking about the hoards of female fans who fill the stadiums at their concerts. After Kevin married his girlfriend, Danielle Deleasa, the Jonas clan now have a sister-in-law to add to the bunch, and Nick couldn’t be happier.

MTV News caught up with Nick at his show with The Administration at the Beacon Theatre last week and asked him about the new addition to his family. "I think I knew eventually it would happen," Nick joked. "There's three of us — well there's four including Frankie — I knew it would happen eventually. And so it's good to know it all came together."

Nick couldn’t be happier with the support Danielle has been lending. She was at the show in New York City, watching proudly has her new brother-in-law took the stage in his latest venture. "It's amazing," he said. "She's here ... with her whole family and they're great. I'm so happy to have her [be] a part of our family. It's kind of hard to believe I've got a sister-in-law and it's wonderful."

And we all know the Jonas boys have nicknames for each other (Kevin is "K2," Joe is "Danger," Nick is "Mr. President" and Frankie is "Bonus Jonas"), so it’s only fair that Danielle would get one too. "We just call her Dani," he admitted, adding they have yet to pick the perfect nickname for her. "No, she's just Dani."

What Jonas-approved nickname would you give Danielle if you could?
