Why can't everyone just wait until they perform? Brintey may very well be dire, but on the other hand she may be surprise some people.

In all honestly, even if Britney mimes the whole thing and just stands there looking pretty I'd be happy (but obviously I expecting some sort of routine). Britney is who everyone will be tuning in for, not Miley - no matter how good she sings.

I actually think Britney deserves some respect for going on the X Factor and performing for us, she doesn't have to.
