Katy Perry Performs 'Birthday' at the 2014 BBMAs

Katy Perry joined the festivities at the 2014 Billboard Music Awards all the way from the Newcastle Metro Radio Arena in England, where she put on a neon-packed performance of her latest single, ‘Birthday.’

Sporting a neon pink raincoat and a neon green wig, the ‘Prism’ singer started off the song with a fun dance number across the stage and down the catwalk, assisted by back-up dancers also decked out in neon costumes and wigs.

A lucky girl in the crowd holding a birthday poster caught the eye of KP, who brought her up on stage and put her in a decorated birthday throne. The set was impressive — the throne turned into a spinning birthday cake, surrounded by men in birthday-themed bodysuits showing off acrobatic moves along towering birthday candles.

We’re not sure which part of the performance was cooler — when the birthday girl pulled out her iPhone and Katy snapped a selfie of the two of them on stage, or when the ‘Dark Horse’ star was strapped to a collection of oversized balloons and flew out across the crowd. It was a fun, visually stunning look at the pop star’s Prismatic World Tour.
