X Factor winner Leona visits Sam
Leona Lewis has paid a visit to Sam Bailey in the run up to this week's X Factor show, sparking speculation that Sam could be performing one of the former winner's hits.
This weekend sees the ITV singing contest's 10th anniversary celebration, where contestants will sing hits by the show's biggest stars and there will be some special appearances from X Factor alumni.
Bleeding Love singer Leona, who won in 2006, tweeted a black and white photo of herself with Sam, standing by a piano and what appears to be a print out of song lyrics.
She captioned the photo: "Had a little visit with this lovely lady today @SamBaileyREAL."
Performances over the weekend will come from former X Factor stars Olly Murs, One Direction and JLS.
