When Luke Bryan's wife Caroline made her Instagram page public, she also revealed Brett's Barn. Recently the singer expanded on what his wife has in mind with all of the animals she's acquiring.

Brett is Sadie Brett, the couple's baby niece who succumbed to heart and organ troubles earlier this year. Bryan reveals that shortly after her birth, Caroline promised Brett a white pony.

"Now we’ve turned the white pony that my wife was going to get Brett … we’ve turned our little barn into this place called Brett’s Barn," he tells Taste of Country Nights.

Photos on @linabryan3's Instagram page have kept anyone following updated on the progress, but Caroline is working toward a bigger purpose. “We’re working with some local charities to bring kids out to see the animals and stuff like that,” the "Light It Up" singer says.

By our count Brett's Barn includes a goat named Little Luke, a naughty pig named Jimmy Dean, two mini horses named Bumble and Kilo (Kilo is the white pony) and another goat named Goober Goldsby (GG for short).

Bryan talked to Taste of Country Nights about his family, other new songs from his upcoming studio album and his new single. "Light It Up" is the first taste of his sixth studio album. He and Old Dominion's Brad Tursi penned the song during their first meeting together.
