O.J. Simpson should probably just lay low…not attract attention to himself…but that’s just not in his nature.

TMZ claims O.J. was kicked out of the Cosmopolitan Hotel in Las Vegas after he got wasted…and a little too rowdy.

They say he’s been hitting up the bars at that hotel since his release from prison, and this week he started arguing with the staff!

Security showed up, and escorted him out. Sources say he’s been permanently BANNED from the hotel.

O.J.’s lawyer admits that he was banned from the hotel, but denies that he did anything wrong. (How does that make sense? Why would a hotel just ban someone if they didn’t do anything wrong? SMH.)
