AceShowbiz - Christina Haack (Christina El Moussa) reacted to ex Ant Anstead's claims that she's been "exploiting" their 3-year-old son, Hudson. In new legal documents, the "Flip or Flop" alum denied the accusations by calling them "untrue."

"I have read the Supplemental Declaration of Anthony 'Ant' Anstead and was shocked to see that Ant is continuing to make false allegations against me," she wrote in the documents, which were obtained by Us Weekly. "The allegation that I am 'exploiting' our son is truly offensive and simply untrue."

The HGTV star went on to say, "After seeing what Ant has written in his Supplemental Declaration it is clear that his motivation is not Hudson's best interest."

Firing back at Ant, Christina continued, "I have never exploited our son Hudson. He appeared in a few of my own Instagram ads that each took less than 5 minutes to film. I have all the footage and they were all fun activities that he enjoyed doing, such as a playing with toys or making cookies. These were organic moments in Hudson's eyes. Nothing was forced and they were filmed with a cell phone, not a production team."

"I did not have a problem stopping, nor do I care to feature Hudson in any further endorsements," she added, before accusing Ant of also putting their son on social media. "Anyone experienced in social media will recognize Ant's pattern of posting our son using a product and tagging the product manufacturer as 'fishing' for endorsements. Ant is not currently on television and puts a lot of effort into Instagram since that is his only platform."

Christina's response arrived after Ant revealed his concern about their son amid their ongoing custody battle. In a court declaration on Tuesday, September 27, he accused his ex of using their young child for personal gain, adding that "the risks for a child working on a television production set (even if that 'set' is Christina's home) are innumerable and well documented."

"Putting aside the obvious pressures of working within a TV production environment, children involved in television production often have lingering issues that affect their welfare, worldview, and self-image, leaving them diminished and dependent upon the perceived approval of others for their self-worth," he argued.

The 43-year-old also said that his goal is to make sure that Hudson "is allowed a childhood that is joyful, healthy, and natural, with as few stresses as possible, and this should be prioritized above creating commercial opportunity and content."

In his documents, the "Master Mechanic" star later referenced former "Toddlers and Tiaras" star Kailia Posey's suicide while talking about possible "lingering effects." He wrote, "One of my many fears of Hudson being forced to film reality TV is the possibility that public ridicule over seemingly benign content becomes insurmountably humiliating. I urge the courts to review the recent and tragic case of Kailia Posey and a defining embarrassing meme."
