Congratulations to Kevin Jonas and his wife Danielle -- the two are now the proud parents of a baby girl!

The eldest Jonas Brother and Danielle welcomed their little bundle of joy today, Feb. 2 -- and the proud papa was live-tweeting (almost) every moment.

Earlier today, Jonas alerted fans that today was going to be the big day, writing:

Just a few hours later, the singer tweeted that Danielle was not only in labor, but the baby girl was coming soon:

And soon enough, she did! Danielle's dad, Bucky Deleasa, was the first to post a snapshot of baby Jonas -- and boy, is it sweet. Clearly, she has her grandpa wrapped around her little finger already! "Welcome baby angel," he captioned the photo. "#unbelievable."

Congratulations to the happy couple, and welcome to the world, baby girl!
