Watch Jimmy Fallon & Adam Levine busk in a New York subway station

Jimmy Fallon and Maroon 5 had a surprise in store for commuters in New York City.

The stars dressed in disguise while performing Crazy Little Thing Called Love inside the 50th Street subway station in the heart of Manhattan.

It didn't take long before a crowd formed to watch the seemingly impromptu concert, before Jimmy unveiled their true identities to a completely stunned and unsuspecting audience.  

The performance was part of the latest episode of The Tonight Show Starring Jimmy Fallon. 

Jimmy and Adam both wore wigs and fake beards, rendering them unrecognizable to busy subway commuters. 

'We're gonna do one more song for you guys,' Jimmy said at the end of their song. 'But first I'd just like to say hello, my name is Jimmy Fallon!' he added as he peeled off his fake beard and wig.  

The crowd instantly went wild at the realization they had been serenaded by none other than the late night host and Maroon 5. 

Fans dashed across the platform to watch the singers, and a huge crowd assembled to watch them perform their hit song Sugar.
