Heather Dubrow has a new rival on “The Real Housewives of Orange County.”
The reality star, 55, got off on the wrong foot with Season 18 newbie Katie Ginella, who claimed that the former actress ignored her when they met at “The Real Housewives of Beverly Hills” star Sutton Stracke’s Christmas party before filming.
Ginella, 40, also said that the next day, Dubrow tagged her in an Instagram picture that she wasn’t in.
Ahead of their explosive fight on tonight’s episode, Dubrow addressed her drama with Ginella in an exclusive interview with The Post.
“I think it’s so weird. I don’t know what handbook she’s playing from. I don’t get it,” the mother of four said.
“If you wanna come into a friend group, try making friends,” she added about Ginella.
Dubrow explained that she was initially “really excited” for Ginella to join the show, since the former golf reporter is friends with Stracke, 52, and co-star Gina Kirschenheiter.
“But from the get go … ‘she snubbed me at a party,’ ” Dubrow said. “I mean, do you think that I knew someone was coming on the show … by the way I would never snub someone at a party ever. That’s not who I am. I always say hello.”
“But let’s just suspend disbelief,” she continued. “Would the person I would snub be someone that’s coming on the show? Wouldn’t I wanna make friends with them?”
Dubrow reiterated that she never ignored Ginella when they met late last year.
“There were two girls that were in contention for being on the show. I looked up both of them on Instagram because that’s what we all do,” she explained.
“That’s how she got tagged. My social media girl was putting my birthday post on. She must have been typing in Givenchy, because that was my dress, and Ginella must have popped up.”
Dubrow also revealed an un-aired situation with Ginella that caused more tension in their relationship.
“They don’t show this on the episode, but a few days before the golf event, Katie sent out a text message to the cast and put the wrong Heather on it,” Dubrow recalled. “And then she had to send it to me separately and said, ‘Sorry, I put the wrong Heather on it.'”
“She said, ‘I was doing too many things at the same time.’ I go, ‘I get it.'”
Dubrow also opened up about her relationship with co-star and on-and-off friend Shannon Beador.
“Shannon and I didn’t end after the [Season 17] reunion great, but when she got the DUI I of course reached out to her,” she said. “But she had her own circle, I’m not apart of that circle and that’s okay. But I wanted her to know I was here.”
Before Season 18 started filming, Beador crashed her car into the side of the road and then drove off following an argument with then-boyfriend John Janssen at his house. After cops tracked her down, she was arrested and charged with driving under the influence and hit-and-run.
Beador was subsequently sentenced to three years of probation, 40 hours of community service and a nine-month alcohol program.
“I care about her. I like Shannon,” Dubrow said about her co-star.
“I don’t know why our relationship is always so complicated,” she added. “It’s my fault, it’s her fault, it’s our fault. I don’t know. But I really do love her and I care about her and her kids.”
In addition to starring on Bravo’s OG “Real Housewives” franchise, Dubrow has a new clothing line in collaboration with NY-based fashion designer Susan Bender. Additionally, she has a sparkling wine collection, called GEMS, in partnership with Family Equality who provides resources to LGBTQ+ people who want to become parents.
“The Real Housewives of Orange County” airs Thursdays at 9 p.m. on Bravo.
