Zac Brown – the founder, frontman, and lead vocalist of the Zac Brown Band – is engaged to model and actress Kelly Yazdi, Fox News Digital can confirm.

Brown, 44, reportedly proposed to Yazdi, 31, "a while ago" while the couple was on vacation in Hawaii. A source shared with People magazine that the proposal was "very intimate and the couple has kept it very private."

Although the exact length of the country star and Yazdi's relationship is unclear, the "Hawaii Five-O" actress accompanied the Zac Brown Band on tour for their latest album, "The Comeback."

In July, the Zac Brown Band uploaded a video for Brown's birthday, where Yazdi was seen with a ring on her engagement finger.
