Simon Cowell's desperate plea for Rihanna to join the X Factor as his fourth judge

SIMON Cowell is going all out to lure Rihanna into joining The X Factor as his fourth judge.

The music supremo, 54, has drawn up a hit-list of sexy girls he wants on board and the singer is his favourite.
RiRi sparked rumours she has arranged a secret meeting with Cowell this week after flying into London yesterday.
She caused chaos as she arrived at Heathrow and was mobbed by fans.
Cowell 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.
And that “circus” is exactly what Cowell believes the show needs when it returns.

He 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, 30, 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.
