A Sultry Cover of Britney Spears' Toxic Performed by Alex and Sierra.

The X Factor aired for 3 seasons from September 21, 2011, through December 2013 and it featured a variety of groundbreaking performances. The winners of the final season were Alex and Sierra, an American duo with amazing chemistry and tons of musical talent. They performed a sultry version of Britney Spears’ ‘Toxic’ and you won’t believe how great they sound.

Their performance was so good that they never expected to get the reaction they did. When the audience got up for a standing ovation, Sierra got emotional and had to stop singing. She was so overjoyed to see the positive response from the audience.
