Katy Perry made it like your "Birthday" at Sunday's 2014 Billboard Music Awards, even if she couldn't be there in person because she's touring abroad.
Performing live via satellite from Newcastle Metro Radio Arena in England, she put on a neon-packed rendition of her latest single for the Las Vegas crowd:
Sporting a neon pink raincoat and a neon green wig, Katy was assisted on the catwalk by backup dancers ... also decked out in neon costumes and wigs.
At one point, a lucky girl in the crowd holding a birthday poster caught her eye, and Katy brought her up on stage and put her in a decorated throne.
The "Birthday" throne, of course, turned into a spinning birthday cake surrounded by athletic men in birthday-themed suits showing off their acrobatic moves.
It was a Katy Perry concert, after all.
The pop star also took a selfie with the "Birthday" girl in what turned out to be a pretty fun and visually stunning look at the pop star’s Prismatic World Tour.
