I've found Ayu's Bea's UP magazine cover, I believe!

enjoy! Gorgeous cover, IMO...

It was updated here:

ALSO... I searched for both the 2010 05 editions of Sweet and Scawaii that Ayu should appear on, in amazon.co.jp... the covers are up, but they are NOT ayu.
Sweet (2010 05)

Scawaii (2010 05)

A little confused about that... I wonder why neither are Ayu... o_o
