Rihanna was the surprise guest performer at the 2011 Academy Of Country Music Awards last night.

The R&B singer took to the stage to perform with Jennifer Nettles, wearing a Versace Spring 2011 dress.

I’m sure you’re just as surprised as I am that Rihanna didn’t opt for the runway colourful version. I guess she didn’t want upstage her co-performer.

Rihanna’s more subtle, shorter white Versace halter neck leather dress with a white leather fringe detail falling from the neckline, was again surprisingly pair with simple black pumps.

She was full of surprises.
