It's a showdown of possibly the two hottest naturally brunette babes in Hollywood: Red carpet veteran Demi Moore and preggers beauty Natalie Portman. Both ladies graced the premiere of Portman and Mr. Moore's new rom-com, No Strings Attached, and we want to know who you think looked better. Demi rocked a mini black frock from Carven's spring/summer collection (showing off her perfectly toned gams), while Natalie dressed in a floor-length Vena Cava dress, finished off with fab pumps from Aldo. Not only do we absolutely love their effortless glamour, but they didn't even have to break the bank to look this good! Come February, the Vena Cava maxi will be available at Maryam Nassir Zadeh for $575, and the Carven dress at Opening Ceremony for $830. If it were up to us, this Who Looked Hotter battle would stay at a tie. So you pick: Demi or Natalie?
