There's this Fan-made parody video series that some Japanese people made. It's called "Mahiro's Game Theory". It's a comedy animation video that makes parodies of different video games and animes. If you played a lot games or watched a a lot of animes, you'll immediately recognize all the references it makes.
In one part of the video, there's a reference to Idolm@ster: Cinderella Girls where they are talking about idols and you see a character that looks like Chieri Ogata, but you can't see her face. You'll also see a quick glimpse of a character that looks like Chihiro Senkawa, but of course you can't see her face.
There's no English subtitles right now, but the creator said that later he is planning to add English subtitles. So for now, here's the link:
