Jennifer Lopez came out with a roar last night at the World Music Awards in Monte Carlo, where she picked up the Legend for Outstanding Contribution to the Arts award, performed a handful of her hit songs, and donned three different Roberto Cavalli dresses that literally made jaws drop. Outrageous jungle prints and plunging necklines were the order of the evening as the sexy diva took to the red carpet in a stamped gray and black leopard dress. When it came time to take to the stage, Lopez seduced the crowd in a custom-beaded mini dress from the designer and sparkling thigh-high boots. But the night’s fashion finale came when the singer accepted her award in a backless, one-shoulder tiger-striped Cavalli gown– complete with a feathered hem!–before heading out to celebrate with her husband, Marc Anthony. With so many fierce looks to choose from last night, we’re not quite sure which dress we like best! Tell us: Which one was your favorite look from last night? Vote in our poll below! David Yi
