Singer Katy Perry is happy with her weight and claims she doesn't need to work out because her hectic schedule keeps her in shape.

'I don't feel pressure, as I know I'm kind of voluptuous and I've always been that way. Saying that, I'm young and metabolism is on my side and my schedule is so crazy that I lose weight from the intensity of it,' contactmusic.com quoted her as saying.

The 25-year-old singer is engaged to British comic star Russell Brand.
