While the parents don't know the gender just yet, the former JoBro is wishing for another girl to join their two-year-old daughter, Alena.
Speaking with Nigel Barker on the former ANTM judge's Sirius XM show, Gentleman's Code, the 28-year-old dished:
"I've actually always wanted two girls. I just want a healthy baby, to clarify. I want healthy children. But I've always like wanted two kids that were both girls and my wife was like, 'Why?' I'm like, 'Because I've been around boys so much my entire life that I want to be surrounded by, you know, girls."
He added that another reason is because he and Danielle are "having the hardest time with boy names." LOLz!
The oldest of the Jonas brothers also shared that his wife is keeping healthy by exercising while pregnant because it's "what makes her feel good," despite getting criticism for it.
"It's no one's place to make comments on how you live your life, and you know what, no one even knows whether it was with a nanny, whether it was a babysitter. The baby could have been with her mom or her dad or any of the family members. It doesn't matter who the baby was with. It's not your responsibility to comment on parenting for others. I would hate if someone did that to me."
Hopefully Kevin and Dani won't have to worry about it!
