She was born with her acting family's classic beauty, but Drew Barrymore credits her fun-loving approach to life for her No. 1 spot on People magazine's annual "100 Most Beautiful People" list.
"I just think happiness is what makes you pretty. Period," she tells the magazine. "Happy people are beautiful. They become like a mirror, and they reflect that happiness."
Barrymore, 32, graces the cover of the issue that hits newsstands Friday. It's her fourth time on the list but first as cover girl.
