Rihanna showed off two very different looks — and one very personal piercing — for dinner and then a night on the town in Manhattan last night. Unfortunately, it looks like girlfriend didn't do a flash bulb check on that sheer black top with no bra underneath before leaving the hotel, whoops. Her man Chris Brown wasn't there to appreciate her looking so great in that hot pink skirt, but the adorable duo are flying high on the charts — she has the No. 2 single this week while he is at No. 3. Monday night are the Teen Choice Awards where she's nominated for four awards while Chris got nine nods, so we'll see if this unstoppable twosome scores big yet again.
