Katy Perry has released an 8-minute music video for her latest single “Birthday.” In it, the singer is unrecognizable at five birthday parties.

At the beginning of the video we’re introduced to each of the five characters that Perry becomes for each of the very different birthday parties she’s attending. Hidden cameras appear to be set up at each event.

Perry assumes the role of a clown, an animal expert, an old dancer, a Jewish MC, and a princess at the five parties and the results are pretty entertaining.

Watch the “Birthday” music video below:

In the middle of the video, Perry’s various characters cause a disaster at their respective parties (from an animal out of control to a car crash), and at the end Perry reveals her true identity at the little kid’s birthday party.

“Birthday” is the fourth single off Perry’s latest studio album PRISM which dropped in October.
