Jason and Brittany tied the knot in 2015 in Mexico. They announced the pregnancy in May. "Been hard to keep this secret but we couldnt be happier to add to our family," Jason wrote alongside an Instagram photo of him sporting a "Baby Daddy" tee, while his wife was wearing a matching "Baby Mama" top. "This year just gets better and better. #bunintheoven," added the Grammy nominee.

Brittany, meanwhile, posted, "SURPRISE!!! WE ARE PREGNANT!!! This was the hardest secret we've ever had to keep. 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! All of the moments of heartache were followed by the biggest blessing in the entire world!! We will never take one moment for granted & can't wait to meet you, sweet baby!!!"

The newborn baby is the first child for Brittany and the third for Jason, who is also a father to two daughters, 14-year-old Keeley and 10-year-old Kendyl, from his previous marriage to Jessica Ann Ussery.
