Rihanna is known for her vivid voice, sizzling sex appeal and trendsetting fashion sense, and the 22-year-old had all three on display during Wednesday night's American Idol as she performed her new single, Rockstar 101, and RadarOnline.com has the clip for you.

The Barbadian beauty, who is reportedly seeing baseball player Matt Kemp, trotted out in a black, skintight cat suit and was bolstered by a lavish set that featured guitars, lightning bolts and skulls. She concealed her high forehead with a short, shaggy hairdo she pulled off stunningly.
