Jennifer Lopez Kickin' Ass in South America

Wearing the appropriate diva workout outfit of tight jeans and designer shades, Jennifer Lopez kept her infamous booty in shape by high kicking while practicing the Brazilian dance-based martial art Capoiera in Uruguay on Thursday.

The 42-year-old got her self defense on in the middle of looking for talent in South America for her new Spanish-language talent show "Q'Viva - The Chosen!"

Her boy toy Casper Smart better not mess things up with J.Lo, unless he wants his butt kicked ... literally.
