Even when some of her other roomies didn't have her back, Amber M. still didn't back down.

She throws her drink, but still keeps her cool.

Ailea asks her Fab 4 buddies to hold her back.

Cookie can bring out the worst in people.

Tiffany is usually to coolest bad girl in the house. But sometimes it's the quiet ones that you have to look out for.

In the biggest, baddest fight (so far!), KC and Amber M have an all-out smackdown. Who started it? Well, physically, KC put her hands on Cookie first.

Cookie gets Kayla to back up near the car.

KC starts to pull on Amber's hair.

And she starts to choke her. Who ended up going home? KC!

Tiffany may be the mamma bear, but even she has her limits.

And she warned Kayla to stop the craziness, or else Chi-town was going to bring it!

Would you want to mess with this bad girl?

Tiff looks serious...seriously pissed.

Tiffany can be a fun person -- just look at this candid pic with Marcus!

Tiffany plays the role of peace-maker, but not for long.

She climbs on top of the limo --she's the queen of the world! Later, she says she better not find out that the Ambers made the whole story up. Can you say tensions are growing worse?
