“She’s done too much damage to me,” Judge, 49, told PEOPLE Now on Monday. “Personally, she has no boundaries and so that’s where you’re like, ‘Is that the kind of friend I want?’ ”
Gunvalson, 55, concluded last season on the outs with the other women of the O.C., with longtime on-again/off-again bestie Judge reaching her breaking point when rumors began to swirl about her husband Eddie’s sexuality.
“For everything that I’ve gone through, you know, my marriage is so sacred to me,” said Judge, 49. “For Vicki to insult my marriage like that like it’s a fraud, that’s what hurt me.”
Beyond her personal grievances with Gunvaslon, Judge takes the rumors in stride, noting her husband is a “hot guy, someone says he’s gay — happens all the time!”
“Our relationship is really easy,” she said. “We’re great friends, we’re great lovers … we just have fun together.”
Judge — whose tagline for the new season is: “I’m pint-sized, baptized and highly prized” — said she made an effort to fix things between with Gunvalson, but that it’s a challenge to get along with her.
“I tried my hardest, I really did,” she said. “You can make fun of my outfit or call me ugly, whatever, but you don’t go that low.”
Season 12 of RHOC sees the return of Lydia McLaughlin, the absence of Heather Dubrow and the addition of newbie Peggy Sulahian. Shannon Beador, Kelly Dodd and Meghan King Edmonds return with Judge and Gunvalson.
The Real Housewives of Orange County premieres Monday at 9 p.m. ET on Bravo.
