Bad girls club back 12/4

I saw the first episode and this time around there is going to be plenty of trouble. It started off with a bang.

 

For some reason I came across a marathon of the first season and recorded a bunch of episodes. I watched a couple last night, and I don't understand the premise of the show.

Who are these girls. Is there some special reason they are chosen to live together or are they just a bunch of girls who want to be on tv and are put in a house? I can't determine if there is some bigger premise to the whole thing.
