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.
