Sugarland's Jennifer Nettles is expecting her first child with husband Justin Miller. Sugarland's manager Gail Gellman told People magazine, "They are thrilled beyond belief."

Nettles is due in November, which means the baby will be born close to her and Miller's one-year wedding anniversary. They were married in a sunset ceremony in Tennessee.

Nettles is currently serving as a mentor on ABC's "Duets," airing this Wednesday night at 9:30 p.m. ET.
