Alexandra Burke Has Alter-Ego Like Beyonce

Alexandra Burke says that she has created an alter-ego to help her perform on stage.

Much like her idol Beyonce - who recently unveiled her split stage persona Sasha Fierce - the X Factor star says she is different character when performing, than she is in real life.

Explaining her split personality to The Sun, Burke says: "Beyoncé gets on stage and she's Sasha Fierce, then she's different off stage. It's just like me. I get on stage and I'm a different person to what I am off stage."

Alexandra recently performed 'Listen' live with Beyonce as part of the X Factor final earlier on in the month - you can watch a video of their duet here.
