Kelly Clarkson has debuted a song inspired by the new children's book written by Today anchor Hoda Kotb. The touching song, which is titled after the book "I've Loved You Since Forever," premiered Thursday (3/8) on Today, with a video of Clarkson singing the tune airing during the broadcast. After writing the children's book about her adopted daughter, Haley Joy, and the timeless love felt between parent and child, Kotb thought it would be a nice touch to have Clarkson turn the book's words into music.Calling Kelly an "unbelievable human being," Hoda tells People, "She changed my life. This song is now part of our family history. It's amazing that she did that for Haley and for me and for anyone that listens to it and feels like the song is about them."
