Things Get Nasty in 'Real Housewives of Beverly Hills' Season 2 Trailer

COMMENTARY | If you thought former child star Kim Richards caused some high-dollar drama last season on Bravo's "Real Housewives of Beverly Hills," you may be surprised to learn that she's back for Season 2 of the series.

Richards' return to the show was called into question after her sister, Kyle, called her out for being an alcoholic on the Season 1 finale; the two didn't speak for months after that, according to Us Magazine.

Now, Kim is back, perhaps to show the world the real her. But is it a smart move?

The new season's explosive trailer (and we do mean explosive-- make sure the kids aren't in the room before you watch it!) shows Richards going at it with newcomer Brandi Glanville, the ex-wife of actor Eddie Cibrian. Their heated exchange makes last season's hellish dinner party at Camille Grammer's look like a church social.

In the clip, Glanville looks to be accusing Kim of doing crystal meth while Kyle jumps in to her sister's defense. Taylor Armstrong is on hand to referee the festivities.

In what may or may not be a response to the "RHOBH" trailer, Glanville recently tweeted, "Let's try not to pass judgment until we have ALLLLLL the details people!"

This could mean that the crystal meth comment was directed at someone else, or Glanville is tweeting in defense of herself after backlash from the haters. (Because those "Escape to Witch Mountain" fans can be brutal!)

As for more trailer drama, Armstrong, who recently filed for divorce from husband Russell, looks to be super sad while Lisa Vanderpump has a run in with her former BFF/ houseguest Cedric Martinez.

One Housewife who has noticeably little air time in the trailer is Camille Grammer, who was the show's main attraction last season. But with Grammer's divorce from ex-husband Kelsey finalized, perhaps this season there are bigger fish to fry.

Like Glanville. Though not touted as a series regular, she's a recurring cast member and looks to be ready for a good cat fight. Just ask LeAnn Rimes.

Meanwhile, the "RHOBH" trailer reminds us all of one very important thing: Money can't buy happiness.

"The Real Housewives of Beverly Hills" will premiere Sept. 5 at 9 p.m. on Bravo.
