Sugarland's Jennifer Nettles better brush up on her lullabies!
The 37-year-old Grammy winner and her husband, entrepreneur Justin Miller, are set to become parents, her rep confirms to Us Weekly.
It will be the first child for Duets mentor Nettles and her husband of nearly seven months.
Nettles and Miller -- a former model whom the country star dated for two years before marrying -- tied the knot in a small Tennessee ceremony in November 2011. Sugarland's Kristian Bush was among the close family and friends in attendance.
The mom-to-be was previously married to club owner Todd Van Sickle from 1998-2007.
