During a game of "Throw Me a Line" on The Kelly Clarkson Show, Gwen Stefani's fellow coaches on The Voice, Blake Shelton, John Legend and Nick Jonas were asked to guess popular song lyrics. When given the line, "A few times I've been around that track," Legend and Clarkson correctly guessed it was from Stefani's 2004 hit "Hollaback Girl," causing Shelton to shake his head in disbelief. Shelton had written a love song for Stefani for their wedding vows with the help of songwriter and producer Craig Wiseman.
