Rihanna 'Vogues' it at Fashion Rocks 09.

Check out the above clip of Bajan/Int'l star Rihanna doing her fash thing and belting, nay, lip-syncing a cover of Madonna's classic 'Vogue' to open the 2009 Fashion Rocks show.

Now, the video is grainy, and it's just a clip, but you can get a general gist as to how she sounded during the performance.

I can't say for certain that she lip-synced, but it was kinda fishy. I mean, I've heard Rihanna try to dance & sing live; it's not quite a treat.

But during this performance - where she looked absolutely 'Josephine Baker' fab - she slinked and strutted all over the place, sometimes mouthing words that didn't match up to what was being played on the speakers!

I tell you, she sounded extra smooth. Well, maybe she's been practicing...
