Angelina Jolie and Jessica Alba better watch their backs because a new sexiest woman in the world has just been crowned. Transformers hottie Megan Fox has just topped FHM's annual 100 Sexiest Women in the World poll of FHM readers. Besides Angelina and Jessica, Megan out-sexied Rihanna, Paris Hilton, Scarlett Johansson and Hilary Duff. Jessica Biel came in as runner-up. And in a nod to her continuing allure to members of the male persuasion, Britney Spears rounded out the list at No. 100!
