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!" 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. "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."

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.
