Let the catfights begin!

Real Housewives of Beverly Hills is back on Bravo tonight, and this teaser clip of the new season shows us everything we need to know about how well some of the ladies are getting along. Lisa Rinna and Lisa Vanderpump are at each other's throats over those Munchausen syndrome claims surrounding Yolanda Foster's illness last season, and it doesn't appear they are going to be able to kiss and make up anytime soon.

There's a new girl in town, too! Dorit Kemsley will join the cast in place of Foster, and she seems like a pot stirrer.

As for the witty opening credit taglines? "The crown is heavy, darlings. So just leave it where it belongs," is Vanderpump's, while Kemsley's is "When you've traveled the world, you can speak in any accent you want."

If Andy Cohen really wants ratings he would bring back Brandi Glanville, just sayin'!
