Say it ain't so! Jana Kramer and Brantley Gilbert have ended their engagement.

I just read in People that the couple have credited their busy careers as the reason for their breakup.

Having just seen both of them this summer, I'm saddened by this news -- I was rooting for them. This leads me to wonder who will get custody of their dog Junior.

Both were as Best New Artist nominees at the ACM Awards this year.
