Crystal's attitude doesn't bother me at all. I think that she is just an easy going, simple person who is confident and knows what she can do. She doesn't appear to be a talker, staying quiet for the most part. If she were out there running her mouth, I might think a little differently.
I totally agree. I don't see her as cocky or arrogant at all. She may be confident, but why shouldn't she be? False modesty is a lot more of a turn off to me than confidence.
I actually see her as someone who has had a tough life (but doesn't play it up), and really isn't all that impressed with the glitz and glitter. While Siobhan is all about the performance, I think Crystal just is more of an introvert, and really only cares about getting into the music.
