Lee "Q" O'Denat, who founded WorldStarHipHop in 2005, has died at the age of 43.

According to TMZ, he passed away last night in his sleep. Sources suspect a heart attack.

WorldStar started as a mixtape website, but evolved into a clearing house for fight clips, music videos, news and just about anything virally.

Along the way, it became one of the most popular websites in the world, and yells of "World Star" became ubiquitous whenever two (or more) people began fighting.

Q explained his website in an interview with the New York Times.

“Hip-hop is for the sex, the drugs, the violence, the beefs, the culture,” Mr. O’Denat said. “That’s the competitiveness of hip-hop, so I felt like the site needed to be R-rated.” He added: “People may be offended by some of the content, but, hey, the Internet is not a censorship boat. We’re the Carnival cruise, man. You don’t have to log on.”

Update: According to TMZ, Q did die from a heart attack, and the San Diego County Coroner has listed "obesity" as a contributing condition. Q, who was on a weight loss regiment, failed to respond to CPR, and was pronounced dead on the scene.
