Jason Aldean's daughters predicted it: The country star and his wife Brittany are having a girl! The new baby will be the couple's second child together.

On Sunday (Aug. 12), Aldean shared a video of the family doing a gender reveal stunt, just the five of them. As Brittany Aldean explains to the camera, she and her husband already knew their second child's sex, but they wanted Aldean's daughters Keely and Kendall to find out in a special way.

Before smashing open "baseballs" filled with pink dust, both Keely and Kendall predict that Brittany is having a girl. Turns out, they guessed right -- and are pretty excited about the impending arrival of their new little sister.

The Aldeans revealed in early July that Brittany was pregnant with their second child. The two welcomed baby Memphis, their first child together, into their family in December; the boy earned his name thanks to his father's love of Elvis Presley, and his middle name is his father's stage name, Aldean. Jason Aldean changed the spelling of his own middle name, Aldine, to use as stage name; Aldine was also Aldean's grandfather's name.

Aldean and Kerr have been married since March of 2015. Keely and Kendall are Aldean's daughters from his first marriage; the two helped their dad and stepmother with their gender reveal for Memphis in 2015 as well.
