Katy Perry is such a tease, rolling into a Santa Monica studio with a top secret envelope labeled KP4 ... a not-so-subtle hint at her upcoming album.
She's technically released 4 studio albums already, but only 3 have been under the stage name Katy Perry. She used to go by Katy Hudson.
She just threw down $19 million for a new Bev Hills mansion, but you'd never guess it looking at her. Don't let the dressed down rollergirl look fool ya ... the lady's filthy rich.
