Beyoncé is said to be in talks to sing a duet with X Factor finalist Alexandra Burke.

Show supremo Simon Cowell is reportedly looking to strike a deal with the singer which would see her perform in the final of the talent contest.

Burke, who last week sang Beyoncé's 'Listen', has become the bookmakers' favourite to take the X Factor crown.

She expressed her surprise at the support after performing at a secret gig earlier this week, saying: "It's very, very scary. I got that news yesterday. It actually shocked me as I wasn't expecting that."
