Take it off!

Katy Perry -- the daughter of two pastors -- poses nude on the cover of her new album, aptly titled Teenage Dream (in stores Aug. 24).

"Oh my God, what will my mother think?" Perry, 25, said after showing off the cover for the first time on Ustream live Wednesday.

"It's so gorgeous. I'm so excited. I'm nervous. I'm shaking a bit. This will be my first piece of real art," she went on.

The cover art, painted by artist Will Cotton, is even scented.

"We went through every detail -- it even smells like cotton candy!" said Perry. "It actually stinks."

This isn't the first time she's shown off some skin. Perry went topless in her video for "California Gurls," and the June issue of UK Esquire.
