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 Beyoncés hit Listen.

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