The Swon Brothers star popped the question to Caroline on Saturday night (25Feb17) during a special movie date, for which they were joined by their families.

According to The Tennessean newspaper, Colton had local theatre bosses insert a highlight reel of the couple's most memorable moments in between trailers for upcoming movie releases, and after the clip aired, he got down on bended knee.

Sharing the news with fans on Instagram, he wrote, "She said YES! I get to marry my best friend y'all (sic)!

"I've been dreaming her up my whole life and she's so much more than what my simple mind could come up with.Thank you Lord for this amazing girl and these two amazing families. Forever ain't long enough (sic)."

The couple met in 2013 when the Swon Brothers and Glaser both competed on hit talent show The Voice. The sibling duo, comprised of Colton and his older brother Zach, came third under the mentorship of country star Blake Shelton.
