5. Olivia Wilde
Rank last year: 1
Last year’s Hot 100 list topper may have slipped a few notches, but it’s not because we love her any less. The House star took a break from television this year to work on films like Tron Legacy and Cowboys and Aliens and to grace the covers of several women’s magazines, proving that the world at large finally knows what we have since we first saw her on The O.C.: Olivia Wilde is hot. For the record, it’s not just her eyes or her smile (or her banging body), we also appreciate her philanthropy and willingness to stand up for causes she believes in, especially the education and health of Haitians. And the good news is she’ll be back for the eighth season of House in the fall.
