The Real Housewives of Orange County

Vicki considers buying a yacht.

Tamra's husband quit his job.

Tamra and Simon Barney celebrate their ten-year wedding anniversary with a weekend getaway in Napa, and they invite Vicki and Donn to join them. While Tamra and Simon enjoy a romantic weekend of wine tasting, grape-stomping and gourmet dining, Vicki and Donn struggle just to be nice to each other.

Gretchen hosts a burlesque party at her home.

Jeana, Vicki and Tamra celebrate the Fourth of July.

Gretchen gets Jeff's children to visit him in hospital while she hangs out with a friend. When Tamra tells Gretchen off, the fallout is catastrophic.

The ladies go to the racetrack.

Vicki Gunvalson visits her family in Chicago and once again tries to get validation from her less than affectionate mother. Gretchen Rossi is taking care of her gravely ill fiance, Jeff, and reaches the end of her emotional rope. With Simon's urging, Tamra Barney takes an etiquette class and hires a top chef to prepare a formal seven-course dinner for all the housewives, which includes premium tequila tasting. When the tequila shots are served, Tamra and Vicki set Gretchen up for a major fall.

With Tamra Barney's formal seven-course dinner winding down, Tamra's son Ryan sees an opportunity to make his move on a very drunk Gretchen Rossi, leaving the rest of the ladies to worry and wonder about Gretchen's well-being. The ladies travel to Santa Monica for a trendy shopping day. Over lunch, when Gretchen confides in the women about her finances, it sparks a heated argument between Lynne and Vicki.

Vicki and Jeana travel.

With her wild 18-year-old daughter, Alexa, running circles around her, Lynne Curtin seeks her mom's advice about how to be a better parent. Vicki Gunvalson comes to a surprising decision regarding the purchase of the million-dollar yacht she so badly wants, and after two grueling months in the hospital undergoing chemotherapy, Gretchen Rossi's fiance, Jeff, returns home. Later, the housewives blow off some steam with a girls' overnighter in Las Vegas.

Jeana Keough and her daughter, Kara, drive up to Berkley to move Kara into her apartment and find themselves strangers among the "bums" and "hippies." Tamra Barney visits her dad in Iowa and puts it all on the line, spilling her heart out to her estranged father, while Gretchen Rossi does Dallas, reuniting with her four best friends from college.

Jeana Keough has her first real date since kicking her ex-husband, Matt, out of the house. Vicki Gunvalson's daughter, Briana, has a new plan for her life that leaves Vicki stunned. It's the end of summer and all the Housewives, past and present, get together.

Hosted by Bravo programming executive and "Watch What Happens" host Andy Cohen, the ladies of Orange County reunite to dish on all drama and give their side of the story on what really went on after the cameras stopped rolling.

Bravo returns to the real-life Peyton Place that is the exclusive gated community in Orange County, Calif. with never before seen footage from the dramatic fourth season and explosive reunion special.
