This n***a ain’t sh*t! Seriously. He somehow managed to downplay the fact that he beats women for fun – by faking his engagement to some random scuttlebutt – to turn around and catch THIS charge???

According to TMZ, Mayweather was popped by Vegas one-time on an arrest warrant last night at a casino. After being spotted by Top Flight Security Of The Casino. SMH.

TMZ has learned Floyd Mayweather was arrested in Las Vegas last night, in connection with the warrant that was issued for his arrest for allegedly assaulting a security guard.

We’re told Mayweather was at a casino on the strip when a security guard recognized him and called the Las Vegas police.

Mayweather, who was all smiles in his latest mugshot, is still in custody.

As we first reported, a security guard patrolling Floyd’s gated community claims the boxer poked him in the face when confronted about a parking violation.

If convicted Mayweather faces a maximum of 6 months in jail.

Seriously? You’re gonna put your career in jeopardy to poke some random dude in the face and slap chicks around? You ain’t sh*t, Floyd Mayweather.

And stop smiling in your friggin mugshots. That sh*t is NOT CUTE!
