WATCH: Beyoncé joins Nicki Minaj on stage for TIDAL concert in New York
Beyoncé surprised fans when she posed as one of Nicki Minaj's backing singers.
Both Beyoncé and Nicki Minaj were set to perform at the TIDAL concert held in New York, but no one expected it to be quite like this.
Voluptuous Nicki took to the stage dressed in a low cut black corset, black lace stockings and boots surrounded by dancers also wearing black, to sing her single 'Feeling Myself'.
After the first verse the 32-year-old singer moved to the edge of the stage to reveal more dancers, this time wearing pink facing away from the audience. As the middle 'backing dancer' turned around the audience were surprised to see that it was Beyoncé with her own dancers.
Nicki then joined Beyoncé centre-stage to sing the rest of the song.
The performance was described by one fan on Twitter as the "BIGGEST moment in recent music history!".
While another described it as "perfection".
After the show both Nicki and Beyoncé took to Instagram posting their own photos from the night.
Tidal X: 1020 amplified by HTC took place on on the 20th October at the Barclays Center, Brooklyn, New York held to support charities via New World Foundation.
