Shannon Beador's weight and martial problems are the star of the Real Housewives of Orange County and the star ends up having a major blow out (the first of the season) with Lydia McLaughlin, while stuffing her face with nachos!

Episode two opens with Beador's misery about her ballooning weight and crumbling marriage, as she tells her friend Elaine, a Feng Shui expert, "Things were a little better" in the old house and after she and her estranged husband, David Beador, happily renewed their vows.

She tries to blame her weight gain on stress created by costar Vicki Gunvalson, who she said was "making accusations about David."

A quick scene switch in the show goes to Gunvalson, who is stressed about moving to a new office, but also discusses Beador's Feng Shui friend, calling her theories "such a crock of [expletive]."

Meghan Edmonds was up next, in her Palm Springs house with husband Jim Edmonds and their new baby Aspen — who was in the same outfit from last week's episode!

Jim constantly criticizes the new mom, telling Meghan, "Don't hold her like that, flip her around like that."

As they prepare to drive back to Orange County, Jim makes a mean comment about their dog, saying, "Put her on a leash and tie her to the bumper."

Megan opens up more about motherhood, admitting that it is tough for her and saying that she is dreading getting into the middle of the fights with the ladies again, but that is her only appearance on the episode.

Lydia McLaughlin meets the new RHOC star, Peggy Sulhain, and is stunned to learn about her double mastectomy.

"I'm ok," Sulhain tells her at a photo shoot with her husband. "My mom passed away from breast cancer. To avoid going through that I went all out and did a double mastectomy."

A clearly speechless McLaughlin struggles to find her voice. "Wow. That's like a big story Peggy. This is a lot to hear when I'm first meeting somebody," but she lightens the mood by telling her: "If you're looking for a distraction you should meet some of my friends."

Tamra Judge is planning a huge second birthday party for her granddaughter, Ava, where ALL of the drama finally happens.

Her son Ryan Vieth's fiancée, Sarah, explains that she invited Gunvalson's daughter, Briana, to the party, which upsets Judge.

"It's going to be really awkward for me. To be honest. I love Brian but after what I've been through with Vicki last year, I cut ties with Briana. I just didn't want to see Vicki's face. I was just so hurt by what Vicki has done."

Sarah warns her, "You just need to keep your distance."

Kelly Dodd is up next and her marital issues are all she talks about. "Michael and I are a little bit better now," she admits. "Last year at this time we were not in a good place. But we're both trying to work together in the most positive way we can."

So they go to a gym together. "They say the best way to a happy marriage is play together stay together. Michael and I work out three times a week together. That's about all I can handle with him," she jokes.

Dodd says she understands Beador's troubled marriage . "I'm not a perfect wife. I can relate to Shannon. Marriage is a hard work."

Beador's daughter's first formal is an emotional time, and she admits that the problems with her husband have hurt the family.

"It's hard to watch your children grow up. My family has been through the ringer. Any parent that exposes their kid to their marital issues feels guilty and I feel guilty."
