According to the latest reports today Simon Cowell has drawn up a hit-list of sexy girls he wants on board and the singer is his favourite.
Top of his list is Rihanna, who sparked rumours she has arranged a secret meeting with Simon this week after flying into London yesterday.
Simon believes the 26-year-old beauty would bring an edge to the show.
Not only is she a global superstar, with record sales of more than 150million, she constantly hits the headlines with her outrageous outfits and wild lifestyle.
Simon is determined to put the ITV show back at the top of the ratings and steal the spotlight away from BBC rival Strictly Come Dancing.
Cowell also believes that having both Rihanna and Cheryl Cole, on the panel would make it the sexiest line-up ever.
Cheryl, who Simon has agreed to let help him select the final judge, is desperate for Rihanna to sign up, too.
A source told the Daily Star: “Simon and Cheryl have two months to find someone to sit in that chair and they want to get the right person.
“Rihanna would be a shock selection because she is not an obvious choice for a family show – but that’s what he wants.”
Other candidates include Joss Stone, Ellie Goulding, Mel B, and Black Eyed Peas star Fergie.
