Luke Bryan and his family are big celebrators of anything — big and small — in their household. So when the superstar's wife of nearly 15 years, Caroline Bryan, hit a major milestone on social media, he wasn’t going to let it go unnoticed.

“My baby hit a million. She won’t brag but I will,” Bryan says in the caption of the photo.

Caroline was quick to respond to her husband’s affirmation, but was modest. "Oh stop … that makes my arm pits sweat," she writes.

But why is she so popular? It shouldn't come as a surprise that so many people love Caroline and her antics if you follow her on Instagram. She keeps it real, showing the glamorous — and not so glamorous — parts of her life as the wife of a megastar, which can be chaotic at times.

Together, Bryan and his wife raise two boys, Bo and Tate, as well as their nephew, Til, and nieces Jordan and Kris. In December, Luke and Caroline will celebrate 15 years of marriage.

Caroline and Luke are hysterical together, and they're kind enough to share their love and home life publicly on social media Getting to see videos of them being playful together, as a couple and as a family, never gets old.

It's not news that the Bryans are suckers for a good prank, too — following Caroline on Instagram means constantly seeing the ways she can scare the living daylights out of her family.
