Pretty Boy Floyd ARRESTED!

Even though he was well aware a warrant was out for his arrest, Pretty Boy Floyd Mayweather took his riches to a casino in Vegas last night to hit the slots and tables.  A security guard recognized him and called for back-up.

Deets when you read on....
TMZ reports that Floyd Mayweather is still in custody after getting arrested last night.  The boxer allegedly punched out a security guard recently who was patrolling his neighborhood.
If Floyd gets convicted of battery and whatever else he's charged with, he faces up to 6 months in prison.  You couldn't tell by his toothy smile in his brand new mugshot.  WOMP.
*UPDATE* He was picked up in his Rolls Royce this afternoon upon his jail release.  No bail was set.
