Even though Chris Brown and Drake aren't actively engaging one another in a legitimate beef, they are still far from friends.  During Chris' performance of "Everyday Birthday" with Ludacris and Swizz Beatz during the American Music Awards, Drake was seen in the crowd texting the entire time not looking up to even acknowledge that Chris was on stage.

Oh well, at the end of the day as long as no violence erupts between the two young artists they can ignore each other as much as they want.
