WATCH: Katy Perry's in Disguise for "Birthday" Video!

Katy Perry is barely recognizable in the brand new video for her song “Birthday!” In the eight minute video, the singer goes undercover in five different disguises at various-themed birthday parties.

GUYS, PREPARE YOURSELVES cuz it’s time to bring out the big balloons and !” she tweeted, with a link to the premiere.

The beginning of the “Birthday” vid explains, “In April 2014, Katy Perry attended 5 birthday parties…only no one knew it was her!” For the prank, she dresses as a clown, wildlife expert, Jewish man, old woman and a princess.
