Transformers actress Megan Fox has only starred in one movie, but the actress has certainly caught the audience’s eye. Men’s magazine FHM recently released their list of the 100 Sexiest Women in the World, and the sultry 21-year-old Fox has beat out sexy starlets Scarlett Johansson and Jessica Biel for the number one spot. The blue-eyed beauty is a rising star and has signed on to appear in two more movies in 2008. Last year’s number one lady, the currently pregnant Jessica Alba, saw a slight slip to number three spot on the list. Canadian actress Elisha Cuthbert, Hilary Duff, Kate Beckinsale, Blake Lively, Trisha Helfer and Emmanuel Chriqui round out the top ten. Meanwhile, 2004’s list-topper Britney Spears has seen her psychotic antics take a toll on her sex appeal, as she slips all the way down to number 100 on the list.
