Jimmy FallonandJustin Bieberhad a surprise for visitors of New York City’s Central Park, though it appears no one noticed who they were.
The two stars dressed in silly disguises and headed to the famed Big Apple locale for a “Musical Photobomb” challenge, dancing and lip-syncing to Bieber’s hit song “What Do You Mean?” behind seemingly unaware parkgoers.
Wearing suits, wigs, sunglasses, and fake mustaches, Fallon, 43, and Bieber, 24, were entirely unrecognizable.
Both looked to be having plenty of fun. Eventually, their playful energy became infections, with kids and other visitors joining them in dance.
By the end of the clip, Fallon and Bieber ripped off their disguises to the thrill of those around them. “Oh my God, Justin!” screamed a sea of teenage girls, who posed with the pop star for selfies.
