Jennifer Lopez revealed her amazing abs in a sexy cutout dress at the 2014 American Music Awards tonight (Nov. 23). The 45-year-old mother of two looked flawless in the light-colored bandage dress that showed off her toned body to perfection.

With her long hair swept back, her stunning complexion and pretty sparkly accessories -- including a shiny gold clutch -- JLo looked the absolute picture of Hollywood glamour. (We think we see the outline of a slip under her bottom half in a couple of the photos below, but we've got to applaud her attempt at modesty.)
