Jennifer Nettles had a lot to be thankful for this holiday season.
The Sugarland singer
, 37, quietly tied the knot Saturday in a small, sunset ceremony in Tennessee.
Wearing an Alexander McQueen gown, Nettles married entrepreneur Justin Miller at a chapel nestled in the foothills of the Smoky Mountains in front of an intimate group of close family and friends, including bandmate Kristian Bush.
Miller is a former model who's been dating Nettles for more than two years. He appeared in the video for the band's 2006 single, "Want To," and accompanied the singer to the CMA Awards on Nov. 9, where Sugarland took home the award for vocal duo of the year
But the honeymoon may have to wait, since Nettles is performing Wednesday with Lady Gaga
at the Grammy Nomination Concert Live, and hosting the annual CMA Country Christmas special, airing Thursday on ABC at 9 p.m. ET.
