Lady GaGa performed a stripped-down version of new track 'Americano' during the first night of the Mexican leg of her world tour.

The 'Judas' star took to the piano to perform a theatrical rendition of the track, which deals with various social issues that have recently hit the headlines in America.

Describing the track during an interview with Vogue last month, GaGa explained: "[It's] a big mariachi-techno-house record, where I am singing about immigration law and gay marriage and all sorts of things that have to do with disenfranchised communities in America.

"It sounds like a pop record, but when I sing it I see Edith Piaf in a spotlight with an old microphone."

GaGa recently released two different country-specific tracklistings for her new album Born This Way, with the UK version boasting an extra track.

Born This Way is due to be released on May 23.
