Jason Aldean And Wife Brittany Kerr Announce Pregnancy 7 Months After Welcoming Son

Jason Aldean and his wife Brittany are expecting their second baby! They both announced the pregnancy on Instagram with a photo of their son, Memphis, in a onesie that says "Big Brother."

The couple welcomed their first child together, Memphis, in December. Having another baby ASAP only makes sense, Brittany says. Parenting a newborn is already hard enough; why not get it all over with at once?

"The sooner the better," Brittany told People. "You're already doing the diaper thing, you're already doing everything. Why don't we just knock it out instead of getting out of that time frame, and then having to start all over again?"

It's a good point! The new baby will join 7-month-old Memphis as well as Jason's two daughters from a previous marriage, Kendyl, 10, and Keeley, 15.

Jason captioned his photo of Memphis, "Sup everybody…… guess who is gonna be a BIG brother!" while Brittany captioned her version, "Here we go again!"

It took Brittany and Jason a year to conceive Memphis.

The journey wasn't simple or easy.

Brittany was diagnosed with endometriosis, and she eventually underwent IVF treatments.

"The IVF was probably harder than the actual pregnancy, for me, because it was just such a roller coaster and so difficult,” Brittany said in April.

"It’s such high highs and such low lows, and no one really knows that you’re going through it all so you have to just put on a game face and pretend that you’re not giving yourself shots in your stomach every day, all day.”

But it was all worth it, because they ended up with baby Memphis.

"I fought so hard for this little hand…for this little boy I just knew one day it would happen, and it did, and he couldn’t be more perfect to me," Brittany captioned this photo.
