If your dance moves are able to wow America's Got Talent [1] judge Julianne Hough, you know you're doing something right. Las Vegas residents Izzy, 11, and Easton, 14, recently succeeded and impressed not only Hough, but her fellow judges, Simon Cowell [2], Gabrielle Union [3], and Howie Mandel, with their intense contemporary audition. Izzy and Easton took the stage in a preview for Tuesday's episode, and gave a heartfelt performance [4] that brought the crowd to their feet.

Izzy and Easton aren't siblings, but after their five years of dancing together, they consider each other family. "I love dancing with Easton because he's so amazing and nice and sweet," Izzy said. "He's like my older brother." They based their routine on a familial bond, acting as siblings separated by war.

Before their act began, Cowell questioned the popularity of Izzy and Easton's dance style. "Does anybody like contemporary dance?" he asked Hough, a professional dancer. "Yes," she replied proudly. "Me!" Turns out, Izzy and Easton may have turned Cowell into a contemporary dance fan because he certainly looked impressed at the end of their routine.
