Just a year and a half after her own reality show victory, American Idol Jordin Sparks took to the stage of another competition show, So You Think You Can Dance.

This time, though, she came as a fan.

"[Katee and Joshua] did a routine to my song, "No Air," and it was crazy to see how they moved to it. It was beautiful and I totally saw the story. I got chills," Sparks told Us Weekly of the pair's June 11 performance. "I played it 100 times!"
