I myself think Cheryl proved that she CAN sing live during radio one's live lounge, as shown in the clip. Okay, she is not the BEST singer in the world by any means, but the thing is neither is madonna, fergie, britney spears etc. and you don't see them getting half as much sh** as Cheryl does! I think today, music is not just about your ability to sing live - it's personality, originality, style. Cheryl obviously has these things or she wouldn't be making music. Can you imagine how difficult it must be thinking about mentoring your acts and getting to the right places on time on a live show without having to fit a live performance in on top of that? I think it's perfectly reasonable to pre-record it, if it was someone else like madonna doing it then people wouldn't have a problem. Oh, and anyone who slates Cheryl and says she shouldn't be a successful artist because she can't sing live, two words. Katy. Perry. Just check out her performance on X Factor. I love her music. But my goodness do I wish she had mimed. Awful.
