There will always be controversy over this. I've never heard the age rumor but I have heard someone say that Ayumi got liposuction, which is ridiculous since she's really skinny naturally. The age one wouldn't be too weird, though, there are a lot of celebs in Japan who don't reveal their real ages (or lie) and are darty about the subject *coughGacktcough*

I have my doubts about Ayu having eyelid surgery because she had them when she was a kid. Also, in the recent pics where she's not wearing make-up her eyes look very small and have dark rings under them. But you never know, I'll just give her the benefit of the doubt regarding cosmetic surgery.
