Watch the video for Katy Perry’s new single, Birthday!

The Roar chart topper has unveiled the video for her new single, Birthday.

Katy Perry has released the (hilarious) new video for Birthday, the fourth single to be taken from her Official Albums Chart Number 1, Prism.

Katy announced Birthday as her next single at the beginning of the month, unveiling the throwback inspired artwork for the single on her Twitter page.

Earlier this week Katy released a teaser for the video introducing the world to the 'World's Worst Birthday Entertainers'; Goldie The Dancer (who sounds uncannily like Sharon Osbourne!), Yosef Shulem The MC, Kriss the Clown, Ace the Animal Trainer and Princess Mandee AKA Katy Perry (yes, all of them!)
