They aren't ugly at all. They just have um... I dunno. It's like some girls have like this hetero aura, and they just don't seem to have it. If not lesbian, then they gotta be bi. That, or my GAYDAR is off.
Then again, Sterling strikes me as at least a little bi, but I'm not sure might have to be drunk to do it.
It's hard to tell with the more glamorous girls. They are full of surprises.
