Two beautiful babes with totally different body structures trying to outperform each other in this gorgeous cleavage battle. Check out Natalie Portman and Jennifer Lopez at their best. Lopez resorting to a body-hugging short dress at the Boys & Girls Club of America event and Natalie donning a strapless black gown at the premiere of her new movie Black Swan. Although Lopez clearly has a natural advantage here, Natalie has done a commendable job of mustering some drool-inducing cleavage. Check out more pics in the gallery after the jump and pick your winner.
