Dean McDermott's Son Jack Calls Out Mom, Mary Jo Eustace For Creating 'Divide' In Blended Family

Dean McDermott's son Jack, whom he welcomed with his first wife, Mary Jo Eustace, is rooting for his marriage to Tori Spelling, even at the expense of his mother!

The Canadian actor's first son went on a recent social media rant, exposing his mother and accusing her of disrupting their family dynamic.

In a now-deleted post, the 24-year-old called out his mom in a lengthy Instagram post, expressing his anger at particular misinformation that he claims poses a threat to their family's dynamic.

Jack started his post, letting fans know that he could no longer be quiet about Eustace's antics. "Since my parents’ divorce in 2006, I have rarely spoken out as I preferred to stay out of it," he began. "Unfortunately, due to my mother's recent decision to spread information about my Dad, Stepmom, and my siblings, I am no longer able to stay silent."

The young adult continued, explaining that his father chose to step away from co-hosting the "Ex’s & Uh-Ohs" podcast with his ex-wife last week because of how she talked negatively about the "Due South" actor and Spelling. "He also chose to leave due to the producer of the show betraying his trust and divulging private information," a disappointed Jack added.

The San Franciso State University alum then strongly came to his father's defense, saying the 56-year-old had "atoned" for the mistakes he had made in the past, but that wasn't enough. In his words:

"He has grown so much as a person. Up until a week ago, our two families where [sic] living in harmony. With this podcast, it has driven a wedge between our two families and created a divide I am not capable of mending. Sadly, I'm not sure it can be."

In a clear statement to his followers, Jack warned them to take the information dispensed on the podcast "with a grain of salt."

He then pleaded with the "Canada AM" star to stop the disinformation, writing, "From my mother, I ask that you please respect me, and my blended family. Please avoid creating any additional strain on our family dynamic. These past few years have been nothing but peace and happiness, and I ask that we continue to try and keep it that way."

The backlash from Jack comes two months after McDermott and Eustace sparked reconciliation rumors after they posted a picture of them together on social media. In the now-deleted upload shared on the Toronto native's page, the reality TV star shared a photo of him posing with his ex-wife as they twinned in black outfits.

The eyebrow-raising image showed the exes looking friendly and wearing all-black ensembles as they posed, standing next to each other with Eustace fondly resting her head on the "Tori & Dean" star's shoulder. McDermott captioned the post, "Reunited?? #Ex’s&Uh-ohs."

The "What's for Dinner?" reposted the image with a similar caption. At the time, fans suggested that McDermott and Eustace were getting back together given that his marriage to Spelling was going through a rough patch. In September, the couple was seen without their wedding rings.

It also didn't help that McDermott was missing from the family's 2021 Christmas card. However, it turned out that the photo promo was only for their podcast, which the father-of-six has now backed away from.

As for the state of McDermott and Spelling's marriage, the pair seem to be finding their way back to each other. As The Blast reported last month, "The Gourmet Dad" author finally addressed rumors of a broken marriage in an interview.

McDermott confirmed that he would be spending the holidays with his family, unlike last year. He said of their relationship, "Everything is amazing. Everything’s great. We’re having a lot of fun. We’re loving the cold weather and then getting ready for the craziness of Thanksgiving and Christmas…I’m excited."

Weeks after the interview, the family of nine released their Christmas card, and McDermott was all smiles and present. He also recently showered love on the "Beverly Hills, 90210" alum in an Instagram post, calling her his "hot wife."
