Christina
Yes, her voice is great - her image is crap - but Britney can't dress either. I have a theorem (lots of time on my hands)
I was surfing this morning and waiting for waves i was thinking about best dressed lists and worst dressed lists. Its about the publicity. Shes dressing poorly because if she dressed well, she'd look like every other starlet and hence would remain unnoticed.
Also, as far as Hollywood goes - it isnt enough to be thin and pretty with a great voice - because they are usually like that. You have to be noticed (see Christina and Lil' Kim)
Hmmmm, and wherethehell does xtina come from Crosstina? Sounds like a croatian pastry.
