LOL, everyone is posting utterly over-photoshopped fake-pictures of Ayu's lips for comparison? About time to remind you guys on fan-made close-up photos from LA era to prove that her lips still look very decent, just like 15 years ago:
If you ask me, personally I think, these lips look absolutely natural. These close-up should end this discussion, it's too obvious that people are creating new plastic surgery rumors for no real reason.
