Sadly to report that we have lost WorldStarHipHop founder Lee O'Denat -- known as "Q" -- has died ... He passed in his sleep on Monday, Jan 23, 2017.
Q founded the premiere hip-hop website in 2005 when he started posting mixtapes, which gradually progressed into a mash-up of hip-hop videos, fight clips, and other outrageous camera footage.
An autopsy is scheduled for later Tuesday ... although one source tells us Q died of a heart attack. He was 43.
