It's not entirely clear who the little girl in this music video from 2007 is supposed to be. The clip is a very emotional four minutes that tells a story ripped from the pages of the singer's life.

She's also speaking directly to her mother -- that relationship is strained, to say the least. Do you think you recognize this music video?
