Yup, its true. Five Ounces has the skinny :

“One of Kimbo’s sponsors is Reality Kings, and Reality Kings operates a number of pornographic Web sites,” asked Burkholder. “Was there ever any discussion of banning Reality Kings from sponsoring Kimbo on the CBS show due to being on primetime network TV?”

“Yes, Reality Kings will not be on his clothing,” Shaw disclosed.

According to Shaw, the decision to prevent Reality Kings from being a visible sponsor was a joint one between CBS and EliteXC.

As much as I admire the fine work Reality Kings does, I understand CBS not wanting to be associated with it. I mean look at what the knuckleheads in the corporate media are already saying :

If people will watch it, a network will broadcast it. And people—millions of them—have navigated to YouTube to watch a backyard brawler named Kimbo Slice turn massive men into mincemeat.

So what if a little blood spills onto the lens? CBS is banking on Slice to headline a new Mixed Martial Arts series called "CBS EliteXC Saturday Night Fights" that debuts at 8 p.m. Saturday on WBBM-Ch. 2.

...Slice, a former high school linebacker who became the Baddest Dude in Miami by pummeling opponents in brawls that ESPN the Magazine likened to "human cockfighting."

Many of his dozens of YouTube clips can only be viewed by the 18-and-up crowd.

Slice, 6 feet 1 inch and 240 pounds with a bald dome, gold teeth, menacing eyes and an untamed beard that could hide a poor sap's missing teeth, has just two official MMA wins. But he's already the poster boy— sorry, sir, poster king—of the sport.

"He said to me: 'Man, you teach a guy from the streets this kind of stuff, and I think I can go really far in this sport,' " Johnson said. "He said: 'I want to get on the ground and break somebody's arm.' "
