Beyonce Knowles married rapper Jay-Z in April

Beyoncé Knowles is in talks to sing a duet with Alexandra Burke on The X Factor.

The singer, 25, has been approached by Simon Cowell to perform on the final show.

‘It's very, very scary,’ Alexandra says. ‘I got that news yesterday. It actually shocked me as I wasn't expecting that.’

Alexandra, 19, became the favourite to win the show last week after she performed a powerful rendition of Beyoncé’s hit Listen.

Last year Kylie Minogue, Katherine Jenkins and Jason Donovan joined the finalists for their performances.
