Oxygen's "Bad Girls Club," takes on an all new city with a hot new cast and a wild Las Vegas location. A brand new group of seven young women travel to Las Vegas and - in a series first - two of the girls are sisters...twins! "Bad Girls Club" adds some sibling rivalry to its newest cast of young, bold, outrageous and endlessly entertaining women as they jockey for position as the head girl in charge. Each claiming to be the ultimate "bad girl," can they put aside their differences and live together peacefully in a Las Vegas mansion - or will chaos rule?
