Jennifer Lopez’s record sales have sagged but her lauded backside has remained in great shape. The media mogul flaunted her curves for the paparazzi on the streets of New York City yesterday and proved that she deserved Glamour magazine’s title of Woman of the Year.

Lopez will carry her curves to the 2011 American Music Awards on November 20th at 8pm ET where she is set to perform. Other entertainers scheduled to perform at the event include her ‘On The Floor’ collaborator Pitbull as well as Chris Brown, Mary J. Blige, Nicki Minaj and others.
