Rihanna in Germany...

Rihanna performed at the Rheinland-Pfalz Open Air concert in Mainz, Germany on August 18th. She wore a top that got some people,ummmm, questioning the authenticity of her breasts. Well, they don't look surgically enhanced to me. They just look pushed up. Anyway, check out more pictures under the cut, including some from a recent photoshoot she did for InStyle magazine...
