Sugarland's leading lady is expecting a baby! Jennifer Nettles is pregnant with her first child, the singer's rep reveals to People magazine.

The country superstar, who's now acting as a celebrity mentor on the ABC show "Duets," is due in November. The baby will come just as Jen celebrates her first wedding anniversary with husband Justin Miller. The two tied the knot over Thanksgiving weekend last year at an intimate ceremony in the foothills of the Smoky Mountains.

"They are thrilled beyond belief," Sugarland's manager, Gail Gellman, tells People of the parents-to-be.

While baby Miller is the first for the newlyweds, he or she will be the third to join the Sugarland family. Guitarist Kristian Bush has a son and daughter, Tucker and Camille, with wife Jill.

Sugarland is now on their In the Hands of the Fans tour, playing different shows in every city they visit, thanks to set-lists that are determined entirely by fan requests. Click here for upcoming tour dates. The trek wraps up in September -- perfect timing for Jen's maternity leave!
