I, as opposed to the other replies in here, actually think Ayu do speak more than basic phrases of english, she's probably not good at it but I think she could make herself understood if she wanted to. I mainly belive this as she was living in NY for some while during her vocal lessons, and her undying love for the US should, however spoiled (
) she is at least bring her into some situations where she has to try out English.
I think a better 'term for what the black guy you're talking about is would be stylist, I think he works on both her hairstyle and some of her make-up.
I don't think her cell is particularly pretty, lol, too much bling bling à la Paris Hilton.
