Dame Shirley Bassey will reportedly perform and mentor contestants on this year's X Factor.
According to The Sun, the 72-year-old veteran will be one of the star guests on the show.
Robbie Williams has already confirmed that he will appear on the programme for the first time to perform his comeback track 'Bodies'. Former series winners Leona Lewis and Alexandra Burke are also expected to return to promote their respective singles.
Meanwhile, Madonna, Rihanna and Whitney Houston are further rumoured to be on the ITV1 producers' wishlist.
Bassey's estranged granddaughter Tatjana Novak-Kimsey auditioned for this year's talent show.
However, the 17-year-old apparently failed to impress the judges with her rendition of Faith Hill's 'There You'll Be'.
