I first met Katy Perry...
backstage at the Oprah Winfrey Show's 2011 Oscar special; she'd flown all the way from Austria to sing with a New York City public school choir, and I was blown away when she performed "Firework." This month you can catch Katy on the big screen—in 3-D!—in Part of Me, which shows how she got her start and what her life is like on tour. My favorite moment is when she looks at the camera with those ginormous blue eyes and says, "My goal when I'm playing shows is just to make people smile." Katy, mission accomplished!
