Katy Perry has joined the list of ladies not ashamed to show a little side boob.
From COED Magazine: "David Letterman was once interviewing Katy Perry about her upbringing as a good Christian girl. Then the late-night host showed a magazine cover featuring Katy. 'What,' asked Letterman, 'does God think of that?' 'That’s sideboob,' laughed Katy. But Katy Perry’s sideboob is no laughing matter! Katy Perry has, in fact, redefined sideboob. Katy even offers up sideboob when facing the camera directly!"
