Las Vegas is the most famously permissive place in these United States.

But one thing Sin City won't allow is 2 Chainz.

The rapper formally known as Tity Boi claims he's been banned from all the nightclubs and casinos in the gambling mecca.

Everytime I try to go out to a club in VEGAS they say that I'm banned ....I never get a reason ,I never have a understanding, jus NO he ain't allowed .this my 1st time ever putting my business in streets via social media . But this way may receive an explanation. I don't owe no casino .I don't need a marker ... I don't know what the fuck goin on ...

Given Vegas's love for celebrities and potential high rollers, it's a bit odd that 2 Chainz has been banned. Especially since it seems like Mr. Bad Example Chris Brown has the run of the place.

What do you think 2 Chainz could have done to get on the Vegas blacklist?
