Little Big Town's Kimberly Schlapman reveals she adopted baby girl

Little Big Town's Kimberly Schlapman announced on Instagram she has adopted a baby girl named Dolly.

The news came as a surprise to her fans as the country star did not previously reveal her plans to adopt.

The 47-year-old posted a picture Thursday on Instagram of Dolly Grace, who joined the family after a successful domestic adoption, according to the group's publicist. Schlapman and her husband Stephen have another daughter, Daisy.

The Georgia-born Schlapman is one-fourth of the Grammy-winning vocal group, which also includes Karen Fairchild, Phillip Sweet and Jimi Westbrook. Little Big Town's hits include "Girl Crush" and "Pontoon."

Schlapman also hosts a cooking show on Great American Country network called "Simply Southern" and she recently released a cookbook.
