This is the Katy Perry we're used to seeing - crazy, zany but pretty, female and young.
But last night she unveiled the teaser trailer for her new single "Birthday".
And this is how she looked.
Yes, this really is her. "Golden nuggets" and all.
The video is titled the "World's Worst Birthday Party Entertainers".
And included Katy dressed up as "Yosef Shulem" The MC. Still unrecognisable.
As well as Kriss the Clown, burps and all.
Katy then changed again and transformed into Ace the Animal Trainer.
Before unveiling her last character, Princess Madee.
Happy birthday bitches!
Watch the video in full here.
Katy Perry's new single "Birthday" will be out on 24th April, 2014.
