Kelly Clarkson brought a very special guest onstage during a recent show in Las Vegas - her daughter, River Rose. Clarkson, 43, and River Rose, 11, performed the singer's 2015 hit "Heartbeat Song" on Friday, July 18, during the singer's "Studio Sessions" show at The Colosseum at Caesars Palace in Las Vegas. Footage of the performance quickly circulated online, showing the pair dressed similarly in black jeans and t-shirts and leaning into one another as they sang the tune.
