The oldest of the Jonas brothers, Kevin, is the first in the band to reach a personal milestone — he's engaged! Kevin popped the question [1] to his girlfriend of two years, Danielle Deleasa, early this morning at her New Jersey home. He showed up on her doorstep with a ring from Jacob & Co. and went down on one knee to ask for her hand. Congrats to Kevin, Danielle and the whole Jonas clan!
