This sassy singer's red carpet style flip-flops from outrageous (Remember that yellow cube hat she wore at last year's MTV VMAs?!) to gorgeously glamorous looks. Lately, she's toned things down a bit by ditching the primary hair color dye jobs, and donning sweet floor-length floral dresses, like a lovely chiffon Dolce & Gabbana gown she wore to the Dream Foundation's 11th Annual Celebration of Dreams Gala, and an off-the-shoulder Naeem Kahn dress decorated with playful poppies that she wore to amfAR's Inspiration gala.
