The 42 year old mother of four wore one of the best Halloween costumes ever seen by dressing as cartoon character Jessica Rabbit for her annual costume bash held in New York City yesterday. She got the look down with a fake chest and bottom that gave her an hourglass figure on steroids. See more photos after the cut...
