Katy Perry channels the sexy pin-up models of yesteryear for her February GQ cover, and though her striped cutout swimsuit is plenty revealing, it’s her candid new interview where the singer bares it all. If you were wondering what was going on in the 29-year-old’s head before she performed dressed like a Geisha at the American Music Awards this past November, she clearly wasn’t worried about offending anyone. In fact, Perry was quite busy chatting with GQ writer Amy Wallace about everything from literally praying for boobs as a young teen, to losing her virginity and plastic surgery. By now, it’s been well established that Perry grew up in a strict religious household as the daughter of two traveling ministers. While she rebelled by pursuing a career in secular music, her now-famous curves could be seen as the result of years of prayer.
