What a difference four years makes.
In 2009, Chris Brown was arrested after brutally beating Rihanna the night before the Grammy Awards.
But you couldn't tell by looking at them tonight.
Though the two -- who recently started dating again -- hit the red carpet separately, they were seated next to each other in the audience at Sunday night's ceremony.
With her head on his shoulder, Rihanna and Chris both smiled for the camera ... and made my stomach queasy at the same time.
And now, a palate cleanser.
Check out the gallery above to see some more photos from the audience and stage that won't make you want to throw up, like Ellen DeGeneres checking out Katy Perry's cleavage and Beyonce and Jay-Z being perfect.
