As news broke that DJ AM, born Adam Goldstein, was found dead in his New York apartment, friends and fans began expressing their disbelief and grief over the 36-year-old's untimely death. Q-Tip took the stage at San Francisco's Outside Lands festival and announced AM's passing. Tip dedicated his set to his "fallen comrade" and asked for a moment of silence before continuing with his performance.

Other celebs took to Twitter and shared their thoughts on AM's death. "I dont even kno wut to say right now," Kid Cudi wrote on his Twitter page. "A true talent and supporter of mine since day 1. RIP to the big homie forever, DJ AM."

DJ Jazzy Jeff was shocked by the news. The veteran DJ performed with AM back in June and was set team up with him again at the Famous Stars and Straps Party on Sept. 1. "Words cannot express the hurt i'm feeling right now," Jeff wrote. "... I'm still waiting for this to be a terrible joke."
