And that's just a few of the quirky characters we're introduced to in the clip above!

Katy Perry's "Birthday" music video will hit the web this Thursday, and the singer has released a preview of the vid that shows all of her delightful alter egos, including Goldie Dancer, Yosef Shulem, Kriss The Clown, Ace The Animal Trainer and Princess Mandee. Hopefully Katy actually appears in the video as herself though!

Katy recently chatted with CMT's Crossroads and revealed that the vid will be unlike anything we've ever seen. I wish I could say its sexy, but its not, she said with a laugh. Its me at my most insane."

With the help of some makeup and prosthetics, we first see Katy as a sexy granny named Goldie, who earned her name because of her "golden nuggets." We gotta say, we're pretty impressed with how perky Goldie's nuggets are!
