The pop star sings to a lucky fan wearing a polychromatic dreamcoat
Katy Perry performed a showstopping rendition of “Happy Birthday” at the Newcastle Metro Radio Arena for Sunday's 2014 Billboard Music Awards.
The green-haired pop star lit up the stage as she serenaded a lucky fan for her birthday.
Suddenly, she rode a balloon-strapped zipline that lifted her up ala Pixar's “Up.”
The crowd in the United Kingdom cheered in delight as the pop princess made it back down safe and sound.
