Drew Barrymore believes that the secret to being beautiful lies in being happy.
The actress recently topped People magazine's Most Beautiful List, and insists that happiness is what makes people look good.
She told People, "I just think happiness is what makes you pretty. Period. Happy people are beautiful. They become like a mirror and they reflect that happiness."
"If somebody walks into a room and they're drop-dead gorgeous and sexy, it's really fun to look at. But if somebody is giving of their spirit and they make you laugh and feel good, that's a whole other level of beauty."
