X Factor winner Alexandra Burke is set to beat Robbie Williams in the charts this weekend – after selling twice as many copies of her new single as the Angels singer so far.

Both stars appeared on last weekend’s X Factor to perform their new singles with Alexandra singing Bad Boys and Robbie giving the audience a preview of Bodies.

Alexandra is expected to sell more than 100,000 copies of her new record, the BBC has reported – her version of Hallelujah became the best-selling single of last year.

Some viewers criticised Alexandra for her guest performance – claiming that she was miming – but X Factor judge Cheryl Cole stood up for the singer on Chris Moyles’ Radio 1 breakfast show on Tuesday.

She said: “I didn’t think she was miming… It wasn’t a Britney case, definitely not, Britney mimed to her record.

“I was just so caught up in the whole production and performance… I was like having a whirl of a time that I wasn’t even thinking about is she miming or is she not, I was just thoroughly enjoying her entertainment.”
