Does anyone else think it's weird that she's one of/if not the biggest female pop star out now, but we've never gotten bikini candids/hardly any full belly pics. We made a big deal out of it with Taylor, and I say we do it with Ariana's belly button too!
I think it's safe to say that Adriana's fanbase has a fair amount of fans who watched her on her Nickelodeon series, which did pander to navel fetishism every now and then. While Taylor hides her bellybutton like a government secret, at least Adriana has her Nickelodeon years for us to fall back on.
To be fair, Taylor seems to be getting ever so incrementally less shy about exposing hers. Maybe she's finally catching on to the fact that if she occasionally just freely lets it show (like most other gals around her age), people will stop focusing on it and turn their attention to something else (except us, of course).
That said, Ariana's navel exposure going down to virtually zero in the last couple years is a bit puzzling.
