Megan Fox is hot, no question, but after she starred in “Transformers,” everyone can feel the heat. Fox was named the world’s sexiest woman in FHM’s annual online poll (nine million cast votes) this week. The 21-year-old American actress, who was ranked No. 65 last year, took the title from Jessica Alba, who dropped to No. 3. Jessica Biel is No. 2. Elisha Cuthbert, Scarlett Johansson, Emmanuelle Chriqui, Hilary Duff, Tricia Helfer, Blake Lively and Kate Beckinsale round out the top ten. Three women from the “The Hills” made the list: Heidi Montag at No. 44, Audrina Patridge at No. 80 and Lauren Conrad at No. 95. See the list at FHMonline.com
