Beyoncé 'the perfect X Factor guest'

Rex Features

Beyoncé has apparently been proving herself the perfect guest star to perform on The X Factor.

A show insider said that there has been no diva-style posturing from the former Destiny's Child singer, unlike reportedly disruptive behaviour from Britney Spears two weeks ago.

The mole also revealed that Beyoncé has been getting into the spirit of the competition, telling The Sun: "Unlike Britney Spears, Beyoncé has followed the show a bit and knows who all the acts are. She has no extreme requests, she’s very sweet. There’ll be no dramas with her on set."

Beyoncé will perform a duet with Alexandra Burke in tonight's final, while Eoghan Quigg will sing with Boyzone and JLS team up with Westlife.
