Kevin Jonas and his wife Danielle have welcomed their second child, a baby girl, and his younger brother Nick spilled the beans via Instagram on Thursday. "We have another Jonas!!" he captioned a video of himself on set, adding, "Can't wait to meet that beautiful baby girl very soon." Nick became an uncle for the first time back in 2014 when Kevin and Danielle's daughter Alena was born. The couple, who tied the knot in 2009, shared news of Danielle's pregnancy back in April and revealed the new baby's gender (with Alena's help) a few months later. Congrats to Kevin and Danielle (and Uncle Nick) on their growing family!
