The X Factor will be transformed into Studio 54 this weekend when an all-time-great disco band perform.
Let's hope Simon Cowell busts out his vintage leisure suit because there's no doubt he'll be jiving when the great Sister Sledge open The X Factor's Disco Week with 'We Are Family' on Saturday (November 12).
The ladies who brought us disco bangers 'He's The Greatest Dancer', 'Lost in Music' and, of course, 'We Are Family' are taking time out from their UK promo tour to bring us back to the groovy '70s.
