SYTYCD Finale Performances! J-Lo, Mary J. Blige, Adam Lambert, & Leona Lewis

Jennifer Lopez kicked the naysayers to the curb in her sparkly heels with a performance of her first single “Louboutins” on “So You Think You Can Dance.” Now that's the way you perform J-Lo. It made sense this time around, she looked stunning, and the choreography was great! Mary J. Blige, Adam Lambert and Leona Lewis also performed their new singles on Wednesday’s season finale.
