I wonder why people don't seem to realise that Ayu has been doing weird things with her lips her ENTIRE career...?
She also has done the whole 'bug eyed' thing forever. In fact, I'd say that some of her shoots from years ago were more fish-lippy (whatever that actually means ^^;

. This is a pout, pretty much every girl I see in Japanese magazines is making this expression.
I think she looks quite cute.
