Thats just the way she is. She doesn't have to be with anyone to have that kind of behavior when being interviewed. I saw it in 2006 when the angels were talking about their first kiss, seperately, and in a VSX interview(when she was being interviewed spereatly) she goes through about 10 different facial expressions a minute when she talks. I don't have a problem with it because adriana doesn't come off like that in photos, and if she didn't show that, what I think is a dorky/goofy side, people would judge her in a bad way kinda how people give candice grief all the time because of the way she looks. Adriana has one of those faces where you wouldn't think she was likeable or entertaining. So I like that underneath it she is dorky and loud and not boring. It helps her stand out more than she already does.
