AceShowbiz - Christina Aguilera and comedian Jimmy Fallon thrilled New York City commuters on Wednesday, Jun 13 by dressing in disguise for a surprise subway station performance.
The pop superstar donned a mousy brown wig, an oversized floppy hat, and sunglasses to try and hide her identity as she joined a similarly-disguised Fallon at an underground location in Manhattan to pose as buskers.
However, Christina's distinctive vocals immediately drew the attention of the crowds as they performed a cover of George Michael's "Freedom! '90".
After whipping off her costume to reveal her signature bleached blonde hair, she then delivered a rendition of her 2002 hit "Fighter", much to fans' delight.
The impromptu mini-gig was filmed for a segment on "The Tonight Show Starring Jimmy Fallon", which is set to air on Thursday night (June 14).
