Brantley Gilbert and Jana Kramer call it quits after a source told PEOPLE "They are both so busy right now,"... "They are both on the road and have to spend a lot of time apart, which isn't ideal for any couple, let alone a couple trying to plan a wedding."

Sounds like a sad song in the making but, without the cheating boyfriend or girlfriend.

The source went on to tell "PEOPLE" "There was no foul play involved, it's nothing like that,"..."They were happy together but know what's best."

Fame takes out another relationship.

What do you think? Smart move to split or is this something they should have worked around?
