Katy Perry is proud of her curves, but before she was famous, the "Fireworks" singer says the shape of her body was anything but voluptous.

The sexy singer, 26, admits to praying for larger breasts as a young girl. Perry tells Rolling Stone magazine:

    "God answered that prayer above and beyond, by, like, 100 times, until I was like, 'Please, stop, God. I can't see my feet anymore. Please stop!'"


As for her prepubescent shape, Katy adds:

    "I was a lot more rectangular then. I didn't understand my body. Someone in sixth grade called me 'Over-the-shoulder boulder holder.' I didn't know I could use them."
