American diva to perform on The X Factor stage this Saturday
Christina, 29, will be performing songs from her new film Burlesque and Dannii, 39, is reported to have approached the Dirrty singer about a joint number with her boy.
‘A duet between Christina and Matt would be a magical moment – just like when Beyonce dueted with Alexandra Burke during 2008’s final,’ says an X Factor insider tells Metro.
‘Matt‘s voice is phenomenal and Christina can hit notes no one has dreamed of.
‘They would be a perfect pairing no matter what song they sang.’
But an official spokesman for the show says: ‘We’re not confirming any of our guest performers.’
