One of the sexiest things about Katy Perry is her awesome cleavage, but the pop star wasn’t always happy with her body. The “California Gurl” graces the cover of December’s issue of Harper’s Bazaar and revealed how she had wanted a breast reduction at age 13: “I had really bad back problems and was a little bit thicker. Then I grew up and lost the baby fat and said, ‘Hey, this isn’t all that bad.’” We’re glad Katy changed her mind!
