A future Jonas Brothers fan has just joined the world! Indeed, Kevin Jonas and wife Danielle have welcomed their first child. We're definitely burnin' up about this news  but in a good way.

On February 2, Danielle gave birth to a baby girl, named Alena Rose Jonas. Danielle's father, Bucky Deleasa, is the one who broke the news by posting a photo (above) to Instagram of the girl's teensy hand.

"Welcome baby angel #unbelievable," Bucky captions the photo. What a proud grandpa!

Kevin, 26, had let his fans know on Twitter earlier that day that the couple was currently in the hospital, as Danielle had gone into labor. "Here we go we're pushing!!!! #babyjonas," Kevin tweets that morning. "I'm so excited #BabyJonasIsComing."

In the wee hours of the morning, just before the baby arrived, Danielle posted an adorable pic (at right) of Kevin catching a quick nap in a hospital chair. "Daddy is sleeping," she captions the photo.

The couple — whose marriage is the subject of their hit reality show, Married to Jonas — announced their pregnancy in August 2013. "I was overjoyed," Kevin said about learning about the pregnancy. "It's been the most exciting thing in my life so far."

Congrats to the happy family!
