Esquire crowned Scarlett Johansson the Sexiest Woman Alive in 2006. We couldn't agree more. ScarJo is about the same age as the likes of Lindsay Lohan, Nicole Richie and Kate Bosworth, but she has managed to escape the Hollywood starlets' obsession with being stick-thin. In fact, she has spoken out several times against that very subject. "I also think that being ultrathin is not sexy at all," she has said. "Women shouldn't be forced to conform to unrealistic and unhealthy body images that the media promote. I don't need to be skinny to be sexy."
