Season 10 of The Real Housewives of Orange County premiered Monday night, and the decade anniversary of Bravo’s grande dame looks juicier than ever.

Vicki Gunvalson – “the OG of the OC” – asked boyfriend Brooks Ayers, who is battling stage 3 non-Hodgkins lymphoma, to move in with her without any strings.

“It’s like a prenup without a nup,” she said.

Tamra Judge underwent her fifth boob job – but this time without any wives around to support her.

“I have this love-hate relationship with my boobs,” said Judge. “I want them big, I want them small, I want them up, I want them down.”

Continued Judge on how she plans to change this season from last (other than new implants and being a new grandmother): “I’m trying to think twice before I speak that’s not in my nature but I know things have to change. I’m on the outside looking in. I feel alone.”

Shannon Beador’s troubled marriage – which looked to be on a better path during last season’s reunion – was even rockier, as Beador revealed during a couples retreat that husband David had an affair.

“I caught him whispering to this person on the phone,” Beador said during the therapy session. “I knew something was wrong I was told I was crazy. I saw all the hotel receipts. I asked him one last time, ‘Are you having an affair?’ He said, ‘Yes.’ ”

Continued Beador, “I will do whatever it takes to keep my family together.”

Meanwhile, the mansion of Heather Dubrow and her plastic surgeon husband Terry continued to grow, along with its budget.

“Sometimes you want something a little grander,” Dubrow said of the new home, which has its own beauty salon, a closet the size of a three-car garage and 14 bathrooms. “I need the $7,000 sink. Move on.”

And new Housewife Meghan King Edmonds, wife of former baseball star Jim Edmonds, looks to add some “Oh!” to the OC.

“I promised myself I would never marry a professional athlete,” said Edmonds, 30, a native of St. Louis, where Edmonds was a player. “I broke all my rules because Jim Edmonds asked me on a date.”

Continued Edmonds, who busted her hubby for not wearing and possibly losing his wedding ring: “His stepdaughter is closer in age to me than I am to Jimmy. #coolstepmom.”

The Real Housewives of Orange County airs Mondays (9 p.m. ET) on Bravo.
