It’s with a heavy heart that I report WorldStarHipHop founder Lee “Q” O’Denat has passed away.

According to TMZ, Q died in his sleep on Monday night. He was 43.

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 today … although one source tells us Q died of a heart attack.

I extend my prayers to Q’s family during this difficult time.
