Katy Perry Can Thank Nudity For New No. 1

It appears Katy Perry's new role as Defender Of the Clothed is working for her: New album Prism had Perry's best debut ever, and it's already selling out all the other ladies who aren't calling out nudity. Coincidence? Well, probably.

This isn't the first time we've written about Katy Perry's chart-topping powers — Perry also knocked Robin Thicke's "Blurred Lines" out of top place this summer with the debut of "Roar." Now that the entire album is out, she might just be unstoppable: Not only is Prism her best-ever in debut sales, it also outsold all the other ladies by landing the title of best sales week for a woman in 2013.

This comes on the tails of Perry's comments to NPR that she doesn't "feel like [she has] to always get naked to be noticed." They're interesting comments that we've explored before, and, as one Atlantic headline calls it, they are "hypocritical but brilliant." As The Atlantic's Spencer Kornhaber noted, what Perry's doing is actually a pretty savvy marketing move: "It appears that Perry, like any good business person, has identified an unmet need in the marketplace — for G-rated, big-budget dance pop."

And hey, it appears to be working — girl's on top of the world.
