This is the sweetest thing ever!
While performing in Greenville, SC, Kelly Clarkson sang her hit "Piece By Piece." The song was inspired by her husband Brandon Blackstock's constant love for the daughter, River Rose, compared with the lack of attention and care Clarkson received from her own father.
So it was no surprise when Clarkson was brought to tears by the actual surprise of her husband joining her on stage during the song.
Watch the sweet moment below.
