It's not an acting job. "MORE" is a fashion magazine and Maki was featured in one of its articles about how to get a "tempting body". The other people listed (actors, models, etc.) were featured in the same article.
And like I said before, I doubt the veracity of the Shuukan Gendai/Yahoo rumor. After the "Eri's ex-BF" fake rumor and the Arashi threesome/marijuana scandal that also screamed fake, I don't trust them. Again, why would avex have her singing at a-nation if they want to postpone her career?
