Jennifer Nettles Sings New Solo Single on ‘Good Morning America’ [VIDEO]

Jennifer Nettles was on 'Good Morning America' this past Tuesday to debut her new solo single, 'That Girl.'

The singer and Sugarland-partner Kristian Bush are adamant that they are not breaking up, but both singers are taking some time to pursue some solo efforts.

Man, she looks great for just having a baby!

Oh and the song is pretty great, too!
