Garth Brooks' Daughter Allie Colleen Releases Debut Single 'Work in Progress'

"Work in Progress" introduces the mainstream to potential total package Allie Colleen, a 23-year-old Belmont University graduate and the youngest daughter of Garth Brooks.

Colleen co-wrote the song with Marcus Hummon, the hit songwriter behind the Dixie Chicks' "Cowboy Take Me Away" and Sara Evans' "Born to Fly," and studio engineer Greg Beick. Its lyrics admit that there's always room to grow without conceding long-term goals ("I'm the best I've even been, but not the best I'll ever be").

"When I walked in the studio that day with Marcus and Greg, Marcus already had the entire song structure minus the chorus when we all sat down," says Colleen in a press release. "For the first time I wasn't worried about how commercial the song was or what everyone else was going to think about the song. I was just honest. I think that is why we are so proud and excited to let you all in one who we are, as a work in progress."

Brooks shares Colleen and her older sisters August, age 25, and Taylor, 27, with his ex-wife Sandy Mahl. To commemorate the single's release, Brooks shared a photo online of himself, Colleen and her stepmother, Trisha Yearwood. "What a beautiful voice on your grandmother's birthday ... perfect," says Brooks in the photo caption.

Yearwood shared the same photo, pointing even more ears to Colleen's single with an equally sweet caption: "From one work in progress to another, what a beautiful song and your voice sounds amazing!"

If the "Work in Progress" behind the song finds solo success, it'll come in part through the talents recognized by influential radio personality Bobby Bones and others, not just from her family and their loyal social media followers.

"Allie is a pure singer songwriter," Hummon adds. "Her inspiration moves effortlessly from her heart to her mind and out into the world, through her beautiful voice."
