It's been only five weeks since Jennifer "Don't Call Me J. Lo" Lopez gave birth to twins and, magically, the singing sensation seems to have withered down to her pre-baby weight. Though we have often been mystified by what Jennifer does — particularly by her decision-making process post Wedding Planner in choosing which films to star in — her desire to quickly trim down doesn't surprise us in the slightest. To that end, we compared Lopez's figure from before Marc Anthony worked his magic on her urgent uterus to a photo of her weeks before she popped to her stunning appearance last night at the New York premiere of Shine A Light.
