After the ouster of Adam last week, 'The Real World: Las Vegas' (Wed., 10PM ET on MTV) switched it up by adding another female to the cast. And this one came in boy crazy and proud of it.

That didn't sit too well with Naomi and Nany, who decided to defend Heather's honor. Not that she asked them to.

Cookie came into the house flirting pretty hard and heavy with Dustin, who was already in a relationship of sorts with Heather. Add drunkenness to the mix, and this assault on their friend simply wouldn't stand.

If Dustin hadn't been in the room, things would have gotten a lot uglier. At one point he had to physically throw Naomi across a bed, and he had to push both girls back several times to keep them from leaping on Cooke. Cooke, meanwhile, decided to start flirting right there, clearly enjoying being the center of that storm.

Welcome to 'The Real World' in 2011. Remember when you were about something?
