Justin Bieber surprised CMT Awards viewers on Wednesday night by appearing in a pre-taped segment for the show and saying Luke Bryan is hot.
But that was nothing compared to the surprise he had in store for folks on Hong Kong.
The singer and Kendall Jenner, both of whom faces of Calvin Klein, flew into the country for an event sponsored by that beloved clothing brand.
And while Jenner mostly just mingled with fans, Justin hopped on stage.
“Yeah @justinbieber is killin it at he #calvinkleinlive event in Hong Kong," Tweeted Scooter Braun. "Out of no where he took a request and is playing #onetime!"
He also played his classic smash "Boyfriend," snippets from which you can watch here.
