'Real Housewives of BH': Rehab, Limo Fight!

Last night's season finale of "The Real Housewives of Beverly Hills" was scandalous!

The housewives attended Taylor Armstrong's birthday party, which resulted in an inebriated Kim Richards fighting with everyone! In a huge blowout with her sister, fellow "Housewife" Kyle Richards, it was revealed that Kim is an alcoholic.

The episode ended with updates on each of the characters, showing that Kim checked into rehab for a week -- only to check out a week later.

The first part of the reunion special airs next Thursday, Jan. 27th -- and rumor has there will be much on Kim's addiction.

Watch the sisters' limo fight!

Kim and Kyle Richards are sisters with Kathy Hilton and Paris Hilton's aunt.
