In her prime, Liz Taylor was one of the most stunning women in Hollywood, and one of the hottest 25-year-old girls. Who else could have been cast to play Cleopatra, widely regarded as the most beautiful woman to ever walk the Earth, and pull it off? Taylor had her breakthrough role in 1944's National Velvet and went on to light up the screen in movies like Giant and Butterfield 8, where she won an Academy Award. Over her life, Taylor married seven different dudes, so at least she spread the good stuff around. Sadly, as she aged she became a parody of her former self, palling around with Michael Jackson. There's no doubt that Elizabeth Taylor is a girl we want to stay 25 years old forever.
