The song is based on Kotb's new book "I've Loved You Since Forever," an ode to the TODAY show co-host's daughter, Haley Joy.

"Before birds flew over rainbows, and monkeys swung on trees, there was you and there was me," croons Kelly Clarkson in her airy upper register.

Gorgeous vocals aside, it's the backstory that makes the new song "I've Loved You Since Forever" so special. The uplifting tune got its inspiration from Hoda Kotb's new children's storybook of the same title, which went on sale this Tuesday. A close pal of Clarkson's, Kotb had the feeling that the book could become a song, and decided to reach out to the singer to make it happen.

What resulted from the duo's collaboration is a beautiful homage to Kotb's love for her daughter, one-year-old Haley Joy, whom she adopted last year. The song's simple message weaves the listener through a canvas of oceans and animals and trees with the powerful takeaway that true love never feels linear — it's always a cyclical emotion with no start or end.
