Kelly Clarkson [1]'s hauntingly beautiful music video for her song "Piece by Piece" features a very special guest star: her baby daughter [2], River Rose. The song is an ode to the wonderful way her husband, Brandon Blackstock, treats her and River, a stark contrast to Clarkson's negative experiences with her own father. While the simple video may not leave you sobbing like Clarkson's magical duet with Josh Groban [3], River's adorable cameo at the end of the video is 100 percent worth the watch!
