PEOPLE reports that Brantley Gilbert and Jana Kramer have ended their engagement. Both artists are extremely busy with their careers at this point, making it difficult to spend time together.

“They are both so busy right now,” a source says. “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.”

“There was no foul play involved, it’s nothing like that,” the insider adds. “They were happy together but know what’s best.”

The couple had been dating for over a year and got engaged in January 2013.

We wish the very best for both Brantley Gilbert and Jana Kramer.
