this is such a stupid decision if she decide's to do this,
first and mainly the name Cheryl Tweedy is atrocious.
secondly, although she is well known under both names this could cause confusion changing her performer name while she is at a high. She should keep the name Cheryl Cole, to keep the success she has already gained under it.
I'm not even used to calling her Cheryl Cole, since I've known her since the first GA album. Cheryl Cole still sounds yucky after three years.
