Kelly Clarkson had two very special guests at her recent Las Vegas residency show: her 9-year-old daughter, River Rose, and her 7-year-old son, Remington.

River Rose joined her superstar mom onstage at Friday night's show to perform a duet of Clarkson's hit, "Heartbeat Song," and Remy danced along as Clarkson sang "Whole Lotta Woman."

Clarkson told the audience her two kids each picked which song they wanted to perform.

"Both of my kiddos backstage getting ready to join me on stage in Vegas," Clarkson posted on Instagram alongside a photo of River and Remy. "Nothing will ever be as cool and amazing as these two little humans that will always have my whole heart."
