The five ladies and former "housewife" Jo De La Rosa gather to celebrate the lavish wedding of Lauri Waring and George Peterson, who finally tie the knot in a spectacular, sky-is-the-limit fairytale wedding in the third season finale.
In the fourth season premiere of Bravo's "The Real Housewives of Orange County," Tamra Barney, Vicki Gunvalson, Jeana Keough and Lauri Peterson welcome a new housewife to the block, 30-year-old blond bombshell Gretchen Rossi.
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.
While her fiance overnights in the hospital, Gretchen Rossi lifts her spirits by hosting a burlesque party at her home. Vicki Gunvalson and family tour a million dollar yacht that she hopes to buy despite Briana's protests. Vicki, Jeana and Tamra have a girl's night out to get away from the drama in their lives, but a discussion about marriage and ex-husbands turns the situation contentious.
All hell breaks loose in Lake Havasu as Jeana Keough, Vicki Gunvalson and Tamra Barney converge on the river for the Fourth of July. The new housewife prepares for her daughter's 18th birthday party, and an incident at her home spray-tan party tests her patience when her daughter has a bratty fit.
Gretchen asks Jeff's children to come out from Michigan and rotate visits to their father's bedside, and Vicki faces her fear of needles to accompany Briana to the Red Cross to donate blood. Lynne meets the other housewives for the first time at Orange County's hip new restaurant, but within minutes of arriving, Lynne makes a misstep that leads to some very awkward exchanges. Before the night is over, Tamra and Gretchen square off over Gretchen's treatment of her ailing fianc? - completely derailing their budding friendship.
Lauri and George take the family on an RV trip to Wyoming, Vicki and Jeana take their kids to Puerto Vallarta and Tamra considers a breast reduction. Quinn moves the rest of her things out from her ex-boyfriendÂ's house.
