The Real Housewives of Orange County

The Real Housewives of Orange County, the series that started it all, is getting another facelift when the show returns for Season 6 this spring.

According to Bravo's website, Lynne Curtin is not returning. Although she is featured in the trailer for the new season, her bio is not listed. Last season saw Curtin and her financially strapped family evicted from their home on-camera, and Curtin struggle to discipline daughter Raquel. She joined the show in the middle of Season 4 to replace Lauri Waring-Peterson.

Taking Curtin's place is not one, but two, new housewives. According to her bio, Peggy Tanous, 41, is a stay-at-home mom with hopes of re-starting her modeling career and a "dramatic secret" to reveal.

Fernanda Rocha is described as a 34-year-old Brazilian lesbian fitness instructor, making her the first gay cast member in Real Housewives history. [Unless you count Atlanta's Kim Zolciak brief relationship with DJ Tracy Young. She is now expecting a child with boyfriend, NFL player Kroy Biermann.]
