The singer announced the happy news on Instagram.com on Sunday (10May15), when he shared a photo of the couple, with his bride-to-be Hannah Freeman showing off her diamond ring.

He captioned the shot, "Proud to say I'm engaged to my best friend and the most amazing woman I've ever known."

Farr's engagement news emerges days after he insisted in an interview with TasteofCountry.com. that he had no plans to follow his close pal Jason Aldean to the altar in the near future.

The star walked Aldean's daughter Keeley down the aisle when he wed Brittany Kerr in March (15).
