The first part of the "Real Housewives of Beverly Hills" reunion show promises to be an argument-filled, trash-talking affair, but then, why should the reunion be any different than the regular series?

The screaming, crying and airing of dirty laundry doesn't stop just because the gals are all seated and dressed to the nines. The Bravo TV staple promises, and is expected to deliver, some down and dirty name-calling as well.

Kyle Richards, Yolanda Foster, Lisa Vanderpump, Brandi Glanville and Kim Richards are joined by new cast members Eileen Davidson and Lisa Rinna this year, and the two new ladies are just as ready as the veterans to take off the gloves.

The two new players got a rough welcome as they bolstered each other against the likes of Kim Richards, who continually denies her addiction problems and targets the new girls.

Kim's sister Kyle Richards has all but given up hope on her sister, as her need to represent as the responsible sister often outweighs her desire to walk away from Kim.

Most of the storyline this year focused on Kim's wacky behavior at a party and cast mates worried she had fallen off the wagon.

However, her retorts to Rinna and others -- all except ally Glanville -- have hurt the players to the core.

So why should the reunion show -- three parts -- be any different?

Foster's battle against Lyme Disease will be discussed at length in the first of the three parts, and the girls will go over the glass-smashing dinner in part 2. In the third installment, the wives will talk about who has the dirtiest mouth and recall their wild trip to Amsterdam, as reported by Us Weekly.

Foster, who is married to music producer David Foster, struggled back from being bedridden with her ailment and brought the cast on a trip to Amsterdam, where all sorts of fights broke out. And while Kim Richards' sobriety isn't the only worry at hand, Foster discussed the incident where her own daughter had been arrested for driving under the influence earlier in the season.

With the men taking a low profile this season, viewers haven't seen much of Kyle's husband Mauricio Umansky, or Lisa's husband Ken Todd. Todd may simply be fed up with going toe-to-toe with some of the gals himself. It's understandable that Lisa's husband wants no part of the craziness, but a bigger question in viewers' minds is: Where is Lisa's adorable dressed-up Pomeranian pup, Giggy?

Meanwhile, the reunion shows are full of plenty of insults, shouting, fighting and threats.

Davidson and Rinna mix it up with them both telling people to "Shut the **** up" and Rinna telling the gals that "double standards" abound.

Among the other sources of conflict between Kim Richards and sister Kyle was Kim's dog Kingsley, who attacked several people, including Kyle's daughter Alexia.

"Her dog bit my daughter," Kyle Richards screams during the reunion show, the Daily Mail reported.  "My daughter almost lost her hand."

Before the anticipated antics, the season 5 finale will hit the small screen and it may -- or may not -- tie up some loose ends, like showing viewers a glimpse of Glanville's 23-year-old Dutch date.

The first installment of the "RHOBH" reunion show airs Tuesday, March 31 at 9 p.m. ET.
