Just when you think you’ve seen the worst from Rihanna, she shows up with another look that will definitely draw a gasp from you.

The American Pop diva rocked this revealing yellow frock to the Pre-Grammy gala that held in Los Angeles, last night.

She didn’t seem to be really bothered that the dress exposed more than it covered, as she raised her hands and moved freely to the music in the hall.

What do you think, sexy or trashy?
