Sunday nights are sure to stay drama-filled on Bravo with the return of "The Real Housewives of Orange County" March 6 at 10pm ET/PT. This season viewers meet a new housewife, Peggy Tanous, a 41-year old former model and now stay-at-home mom. Also, Tamra Barney will introduce Fernanda Rocha, a 34-year old, hot Brazilian lesbian fitness instructor, who viewers have actually seen in a previous episode of the show.

In Season 6, Tamra Barney moves forward with her divorce from Simon Barney and reveals that she has a new boyfriend. According to Bravo, Jeana Keough comes to Simon's defense by "disparaging Tamra in the tabloids," leading to a heated confrontation between the two housewives. Also, Tamra Barney's ongoing feud with Gretchen Rossi appears to have gotten even worse this season and Tamra's son, Ryan Vieth, will reveal a shocking secret.

We will see Gretchen working on her make-up line and a new "handbag collection."  Will Gretchen and Slade get married? Apparently, all of the gossip regarding Slade Smiley and his child support situation, along with his being a serial-housewife-dater and "freeloader" has Gretchen thinking hard about her decision.

Alexis Bellino still worships husband Jim Bellino, but housewife fame has her wanting more freedom and independence. Apparently, the church-going Alexis launches a line of sexy and revealing dresses. Also, the bad economy has hit the Bellino's hard with rumor of a home foreclosure.

Vicki Gunvalson's insurance business "empire building" has had negative results at home in regard to her marriage with Donn. Will she choose between her business and her marriage?

And new housewife Peggy Tanous arrives. Described as an odd mix between a holistic, new age woman and a wealthy Orange County party girl, Peggy likes her bling, but also likes her clean and natural living lifestyle. Season 6 will show this new housewife trying to reinvigorate a former modeling career.  She also reveals a dramatic secret.

Season six of "The Real Housewives of Orange County" was produced by Evolution Media, with partners Douglas Ross, Gregory Stewart and Kathleen French along with Scott Dunlop serving as executive producers.
