Back in <a href="http://bad-girls-club.oxygen.com/bgc/photos/bgc-episode-3-pool-charks#2…; target="_blank">episode 3</a>, Lauren threw Nikki's clothes in the pool.

By the next episode, Lauren and Nikki were clubbing and hanging out.

Out to lunch with the rest of the girls, Lauren and Nikki start acting out. Notice Lauren's loud burp.

Nikki definitely approves!

<a href="http://bad-girls-club.oxygen.com/bgc/photos/char-says-0&quot; target="_blank">Char</a> thinks they're immature but they're just having fun!

Talk about Bad Girl besties! Nikki can't wait to tell Lauren about a spontaneous hook-up.

Back in <a href="http://bad-girls-club.oxygen.com/bgc/photos/bgc-episode-5-kentucky-frie… 5</a>, Nikki and Lauren joined ex-Bad Girl <a href="http://love-games.oxygen.com/lovegames/photos/meet-natalie&quot; target="_blank">Natalie Nunn </a>and music superstar <a href="http://www.oxygen.com/soundslikeoxygen/photos/kimberlycole.aspx&quot; target="_blank">Kimberly Cole</a> on stage.

Char doesn't give up and keeps getting into their faces. Lauren and Nikki just let her yell. They're too tired to play.

Char's outburst and disregard of furniture does not bother Nikki and Lauren one bit.

Poolside is the girls' fav spot to trash talk the other roommates. Both girls even have chic sunglasses!

The party girls' friendship is still going strong, but will it last?
