Let’s get ready to ruuuumble….online….again.

Christina Haack fired back at her estranged ex Josh Hall this week after he accused the HGTV star of “resorting to low blows” in order to promote The Flip Off, the new HGTV competition series starring Christina, her (first) ex-husband Tarek El Moussa and Tarek’s wife Heather Rae El Moussa, which premieres later this month.

As The Ashley previously reported, Christina and Josh both filed for divorce in July after less than three years of marriage. Shortly after the pair announced their split, it was revealed that Josh had been cut from ‘The Flip Off,’ which had just began filming at the time.

Since parting ways, the exes have continued to spar with each other via public statements and petty social media posts as their messy divorce proceeds.  

According to Us Weekly, Christina and Josh’s latest virtual sparring match was ignited by comments Christina made during a recent interview on Radio Andy’s Jeff Lewis Live. During the episode, Christina revealed that she and Josh will likely head to trial to settle their divorce as Josh allegedly “doesn’t want to do mediation.” 

Christina also made a point during the interview to express how happy she is that she and Josh never had any children during their marriage. She also claimed that Josh “doesn’t have a job” and that she gave him money to live on, but he used the funds to purchase an expensive vehicle for himself. 

“ … He drives a Bentley, so [he’s] pulling a lot of chicks … ,” Christina alleged of her soon-to-be ex-husband. 

Following Christina’s appearance on Jeff’s show, a representative for Josh issued a statement calling out Christina for resorting “to low blows” about Josh to promote her new HGTV series. 

“She should focus on her new boyfriend and stop talking about Josh,” the statement continued, referring to Christina’s rumored new boyfriend, Newport Beach-based CEO Chris Larocca.

“As the great Mariah Carey once sang, ‘Why are you so obsessed with me?’” Josh’s statement continued before throwing out the passive-aggressive line, “We wish Christina the best.” 

After getting wind of the statement released by Josh’s rep, Christina took to her Instagram Story to spew some anger at her ex, whom she accused of being a narcissist. 

“I just threw up in my mouth,” Christina wrote. “Quoting a Mariah Carey song is a new low … even for you. Trust me idgaf about Josh’s life. 

“I do however care about his bts [behind the scenes] tactics,” she added. “Narcissism at its finest.” 

While Josh has insisted that Christina focus on her new relationship, he recently hard-launched a new companionship of his own with Nashville-based model Stephanie Gabrys. 

Josh and Stephanie have reportedly been seeing each other for a few months, and while they’ve been regularly interacting on Instagram since December, Josh shared a photo of the two to his Instagram Story earlier this week in honor of Stephanie’s birthday, seemingly confirming that they’ve decided to officially take their relationship public.

“Happy 35th to this real life [angel],” Josh wrote in his Instagram Story, before going on to tag Stephanie’s IG handle. 

Meanwhile, Christina has yet to comment on her rumored relationship with Chris.
