Luke Bryan and Wife Caroline Create Unique Memorial to Honor Late Niece

Back in February, Luke Bryan's niece, Sadie Brett Boyer, the daughter of the singer's wife Caroline’s brother, Bo Boyer, and his wife Ellen, passed away at just seven months old from multiple health problems.

To honor the little one's memory, Luke and Caroline have created "Brett's Barn," a barn full of adorable farm animals assembled to remember little Brett. Caroline shared the most recent addition, a pony named Kilo, on Instagram Wednesday.

Sweet Brett, here's your pony! Her name is Kilo and she's perfectly perfect. Playful, gentle, and has the cutest little gallop! Little heavy in the rear, but she owns it...has some sass in her step! Kilo is loving life in your barn. Thank you @redemption_road_rescue for introducing Kilo and many other animals to our family. We always knew we would find (for Brett) the perfect pony, but never thought she wouldn't be here to love it. If Brett were still with us, I imagine she and Ellen would braid and put little bows in her mane. My brother would drive all over Tennessee to find the perfect unicorn horn for Kilo...because we all know Brett would've wanted a unicorn! We love you Queen Bee 👑🐝 #brightforbrett #brettsbarn

"Sweet Brett, here's your pony!" she captioned a video of the animal. "Her name is Kilo and she's perfectly perfect. Playful, gentle, and has the cutest little gallop! Little heavy in the rear, but she owns it...has some sass in her step!"

"We always knew we would find (for Brett) the perfect pony, but never thought she wouldn't be here to love it," Caroline continued.

Bryan also shared his own clip of Brett's Barn, posting a video of the menagerie of animals, one of whom stepped on the star's toes.

"Greetings from #brettsbarn," Bryan wrote.

Greetings from #brettsbarn. #brightforbrett @linabryan3
