WHAT THE FREAK??? Look At R&B Singer Tinashe's Body . . . Her Hips Aren't Just FLAT . . . They Curve INWARD!!!


We're not sure that we've ever seen this before, but R&B singer Tinashe might have a "NEGATIVE BOOTY". We've seen flat hips before, but we've never quite seen hips that actually concave INWARDS.

It's ok since Tinashe's new man likes it. As we told you earlier this week,, has seeing DJ Calvin Harris, Taylor Swift's ex man.
