Jason Aldean and his wife Brittany are about to be parents again. The couple has announced that they are expecting their second child together.

Aldean shared the baby news on Instagram on Tuesday (July 10), with a little help from his and Kerr's son, Memphis. In the photo Aldean posted, Memphis is wearing a "Big Brother" onesie and striking a (pretty darn cute) pose.

"Sup everybody ... Guess who is gonna be a BIG brother!" Aldean writes in the photo's caption. He also includes the hashtags #thisdude and #aldeanpartyof6

On her Instagram page, Brittany shared the same photo, and captioned it "Here we go again!" The couple has not revealed a due date or further details.

The Aldeans welcomed baby Memphis 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.

Brittany Aldean revealed her pregnancy in May of 2017, and then announced Memphis' sex later that month with the help of Aldean's two daughters, Keely and Kendall. Both girls are children from Aldean's first marriage; Aldean and Kerr have been married since March of 2015.
