Did you miss the BIG 'Birthday' party and the BIG balloons last night on the 2014 Billboard Music Awards?

Katy Perry set the entire awards out with her performance of her latest single, 'Birthday.' Live from her Prismatic Tour at the Newcastle Metro Radio Arena, the green-haired Katy blew out her candles and made a BIG wish. After inviting an shocked fan who was celebrating her birthday onstage with her and sat her in an spinning cake with an birthday hat on her head. Katy then flew away from the spinning cake in her BIG balloons on a zipline over the audience.
