That's them. I don't know all their names but I know of one...THIA MEGIA. Yes, she's a Filipina. Here's a bigger picture of her that I got from the Official American Idol website.
I haven't been watching the show but I heard her sing during the audition as well as during the Hollywood week. I must say she has the voice alright. I also read online that she also went to perform in another talent show...America's Got Talent a few years ago. I'm not sure how far she was able to make it there. Hopefully she'll have a long run in AI...or maybe even win it. Who knows, right?
