(USA TODAY) - Congrats are in order for Sugarland singer and Duets star Jennifer Nettles, who is expecting her first child with new husband Justin Miller.

"They are thrilled beyond belief," Sugarland's manager Gail Gellman tells USA TODAY in a statement.

It will be the first child for Nettles, 37, who married Miller last November in the foothills of the Smoky Mountains in Tennessee.

The couple's baby is due to make his or her arrival just in time for Mom and Dad's first wedding anniversary.
