A few years ago, I wouldn't have felt awkward to look at a girl who was sixteen's tummy, but now (being 21), I can't because it feels wrong. I don't even know who she is, though, so I guess it's no big deal.
I'd like to add Rihanna to my previous list, if she isn't already there. And Alicia Fox, too, for that matter.
