Jason Aldean planned quite the 30th birthday celebration for his wife, Brittany. The couple — who are expecting a baby boy — spent time with friends in Bermuda, where they relaxed and checked out some of the local attractions, according to photos Brittany shared on Instagram.

"One of the best weeks," she writes beneath an image with some girlfriends, Aldean and some male friends. "So glad I got to spend my pregnant 30th with some of my favorite people." Brittany is seen soaking up some sun with a friend in another picture, with blue-green water at her side and her growing baby bump on full display in a white and grey bikini.

Earlier in the week, Aldean shared an image of himself and his wife in a tree. The “Night Train” singer jokes that it “took some work gettin’ her in this tree, but we made it happen.” The couple have not shared a due date for their baby boy — the singer's first son after two daughters from a previous marriage.

As he prepares to become a father for the third time, Aldean tells Taste of Country that he is enjoying watching fellow country artist Thomas Rhett's road to fatherhood. Rhett recently adopted a daughter from Uganda and his wife, Lauren, is pregnant with another girl.

“I was texting him one day and he was kinda asking me some questions,” Aldean shares, “So I talked to him a little bit about it, because I do have two older daughters."

His best advice for Rhett? That there's not much you can do to prepare.

“I think being a parent — it’s something you figure out along the way,” he says. “There’s no book; there’s no right or wrong way to do it. You just figure it out as you go along.”
