Yeah, she really does seem to be keen to eclipse Britney in some department. I saw another pic from that "whip" series and from the front, one seemed a lot larger than the other, and it looked like more than padding. Uneven post-op swelling?
CA is known to have slightly crazy impulses, and has been quoted as saying that the really loves the idea of going too farand going completely over the line, so who knows where this might lead.
PS, she's just supposed to have had "XTINA" tattooed on the back of her head, just above her neck, where its hidden by the hair, which she'ssuppose dot have been meaningto get done for years. She could certainly afford string implants, and it wouldn't hurt her career, so a few years from now she could be looking like an alternative version of Chelsea.
