Sounds as though Nick Jonas is just as excited as brother Joe about being an uncle.
"I'm actually flying right after this to meet my niece for the first time," the 21-year-old singer continued. "He [brother Kevin Jonas] in love with this baby, it's ridiculous. He sends me pictures every 10 minutes. I think it's just like the joy of his life right now, so I'm excited to go [see] him."
Kevin and wife Danielle welcomed daughter Alena Rose, their first child together, on Sunday—and, happily, they've been quite forthcoming with baby pictures.
Joe Jonas had already shared a photo of a snuggly moment with his niece, and Nick added to the album today.
"My beautiful niece Alena Rose," he captioned the pic, which features the wide-eyed infant, clad in a fabulous little onesie printed with hearts, looking intently at her uncle's face (well, we can't blame her for staring) while he's holding her on the couch.
But before he had a chance to meet her, Nick also joked with Demi and E! News' Kristina Guerrero about what topics to avoid while talking to new moms, like Danielle.
"Never bring up sleep," advised Kristina, whose own little one is 6 months old.
"I won't complain about breastfeeding with a mom, either," Demi added, holding her own for effect.
Nick reassured them, "I was not planning on bringing up boobs."
But he did plan ahead, revealing that he had gifts for mother and baby—he just needed to run home after his interview to pick them up before he went to the airport!
"I got her and my sister-in-law some good stuff," Nick said confidently.
