When "The Real Housewives of Orange County" returns in March, Vicki Gunvalson, Tamra Barney, Gretchen Rossi, and Alexis Bellino are joined by new castmate -- 41-year-old former model Peggy Tanous -- for a sizzling season.

Peggy, who is now a stay-at-home mom of two, is an odd mix between a holistic, new age woman and a wealthy Orange County party girl. So she combines her belief in natural living with her love of bling. This season, viewers will watch as she tries to resurrect her modeling career.

Tamra, whose husband Simon filed for divorce in 2010, also introduces the group to new gal-pal Fernanda Rocha, a 34-year old, hot Brazilian lesbian fitness instructor. [Note: She is the only brunette in the cast photo above.]

But Tamra, who already has a younger, more attractive boyfriend, isn't the only one with marital problems. Vicki, too, filed for divorce since the last season of the Bravo reality show. It seems that her busy insurance empire was a constant source of friction between her and her soon-to-be ex.

Feeling pressure from her girlfriends to take the next step with boyfriend, Slade, Gretchen isn't sure she is ready for another trip down the aisle. She has heard all about Slade being a deadbeat dad, a serial-housewife-dater and a freeloader, and has to weigh all this before she decides whether or not to go forward with him.

As for Alexis, she still believes that husband Jim is her savior and she lets him run the show, but she also confesses that she wants more freedom and independence as a wife and mother. One way she is striving to achieve that is the launch of her new line of sexy and revealing dresses.

Tune in on March 6 at 10 p.m. on Bravo, when the OC ladies try to bounce back from a tough financial year, mend friendships and more.
