Rihanna and Britney Spears performs "S&M" at The Billboard Awards

Rihanna and Britney Spears performed S&M together last night at the Billboard Music Awards. That performance was really disappointing, not so much Rihanna's part but Britney's. She didn't put any effort into that performance what so ever (what else is new).  The part where I was just really over her, was when she came out with Nicki Minaj.

Britney may have lip synced and done it badly, but the dancing should have be on point.  I'm not trying to come down on Brit, I just feel like she can do so much better.

Check it out.
