"It's time to bring out the big balloons!"
Katy Perry has premiered her music video for "Birthday" and now we understand why she thinks it's the most insane she's ever done!
Disguised in five different characters, Katy attended a couple of birthday parties without anyone knowing it was actually her entertaining the guests, except for the lucky kids who were surprised to see their idol in front of them!
If you want to know what we're talking about, watch the official music video of "Birthday" below! Enjoy!
Watch out for "Birthday" here on MYX soon and always remember to #MakeItLikeYourBirthday everyday!
