Chris Brown & Rihanna Cuddle At Grammy Awards

In 2009, Chris Brown was arrested after brutally beating Rihanna the night before the Grammy Awards.
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.
