Rihanna performed a few songs at MTV VMA 2008 on Sept. 7. She was paired with T.I. for one song. During the dress rehearsal, Chris Brown accompanied Rihanna on stage to send her there. Brown sent a strong signal to T.I. and the rest of the stage hands. RiRi looked simply ravishing in her saucy dominatrix get-ups. Those fishnets must be doing the trick.
