Drew Barrymore tops the latest edition of People Magazine's list of the 100 Most Beautiful People.

The 32-year-old actress, who starred in such films as  E.T., The Wedding Singer, and Charlie's Angels, says "I just think happiness is what makes you pretty. Period. Happy people are beautiful. They become like a mirror, and they reflect that happiness." This is her fourth appearance on the list, but her first on the cover.

Also making this year's list are actors Brad Pitt, George Clooney, and Leonardo DiCaprio; actresses Angelina Jolie, Scarlett Johansson, and Halle Berry; and musicians Alicia Keys, Jennifer Lopez, and Pete Wentz of the rock act Fall Out Boy.
