Jason Aldean and his "baby mama" have clearly been planning their pregnancy announcement.
"This was the hardest secret we've ever had to keep," Brittany wrote on Instagram with a photo of the couple in customized T-shirts. "This journey for us has been full of many happy times & also many tears ... The biggest rollercoaster we have ever been on, without a doubt!"
This will be Aldean's first child with his 28-year-old second wife. The 40-year-old musician also has two daughters with ex-wife Jessica Ussery, whom he divorced in 2013.
