Prior to the big show, Rihanna was quite conservative … for her.

The pop star chose a white ensemble for the awards, wearing white slacks and a blouse that had a super plunging neckline. She tweeted to her fans: 

“Billboooooaaaaarrrrrrddddsssss!!!!!! In THE VEGAS!!! Don’t forget to watch me open up the show tonight! #RihannaNavy I love you guys.”
