We don't really know anything about the Oxygen reality show Bad Girls Club or its star Nicole "Nicky" Vargas.

But we do know she was arrested for taking off her shirt and sucking off her boyfriend in a Cape Canaveral, Florida apartment complex parking lot.

The sex act was in plain view of many.  When a concerned citizen confronted the lovebirds, Nicky took her mouth off her boyfriend's dick and began attacking the scold with punches.

The cops were called and Vargas was arrested for unnatural and lascivious acts in public, battery, and exposure of sexual organs. She's now out on bail.

TMZ obtained video of the arrest, in all of its topless glory.
