The most memorable contestant on Sunday night’s ‘X Factor’ auditions was undoubtably Sada Vidoo, a ‘living doll’ who gained four yeses from the judges for her rendition of ‘Love Is A Battlefield’. But while Sada may have been new to British TV viewers, it’s now be claimed that she is actually an established platinum-selling act from Denmark.

Sada describes herself as a ‘living doll’ and turned up for her audition in a big pink skirt and frilly top, causing judge Sharon Osbourne to tell her she looked like ‘a toilet roll holder’. But despite her unusual appearance, Sada won over the judges with a bonkers but brilliant version of Pat Benatar’s ‘Love Is a Battlefield’.

But according to The Mirror, far form being a brand new act, Sada is actually a well established singer and songwriter and has been signed to a record label in Denmark. She is said to have released an album, many singles and even written a platinum-selling dance track.

A source told the newspaper: "Sada Vidoo is ambitious and wants to conquer the world with her music. She sees The X Factor UK as a platform to achieve her dream of becoming an international star.”

Playing down the revelation, a spokesperson for the ITV show commented: ”Anyone can apply for The X Factor whether they are professional or amateur, irrespective of their past experience and all contestants are auditioned on merit. Past experience can not always be featured in the programme due to time constraints.”
