While Dean McDermott and wife Tori Spelling are about to welcome their fifth child together, it’s child support for McDermott’s first child — with ex-wife Mary Jo Eustace — that may see him wind up in court over her charges that he’s eight months behind in paying spousal support, to the tune of $6,000 plus interest and attorney fees.

According to the New York Post‘s “Page Six” column, the straw that broke the camel’s back for Eustace was when she read about Spelling’s mother, Candy Spelling, throwing her daughter a lavish $40,000 baby shower when McDermott was allegedly months behind his child support obligations to son Jack, 18.

Eustace — known to Canadian TV viewers for co-starring on cooking show “What’s for Dinner?” — was married to McDermott from 1993 until 2006, and was reportedly “livid” after reading about the baby shower, which was thrown by a top Tinseltown party planner.

Reports of financial problems have dogged Spelling and McDermott for some time now, including: a lawsuit over an unpaid $400,000 loan; a lawsuit launched by American Express over $87,000 in unpaid credit card debt; and a tax lien placed on them due to more than a quarter-million in unpaid taxes.

However, Spelling has dismissed these reports by saying rumours of the couple’s financial stress began after the publication of her 2013 memoir, Spelling It Like It Is. “It’s no mystery why I have money problems,” Spelling wrote in the book. “I grew up rich beyond anyone’s wildest dreams. I never knew anything else. Even when I try to embrace a simpler lifestyle, I can’t seem to let go of my expensive tastes.”

“It was one chapter,” Spelling told People. “I thought I was being relatable, talking about how celebrities go through financial struggles, too, we make mistakes, too. We’re not perfect, we have made a lot of choices financially with real estate that didn’t work out … and that just escalated into this story about financial struggles, bankruptcy. To this day that haunts me!”

Added Spelling: “I just want that story to go away! We’re doing a great new series, I’m really happy, we’re doing a new show on Cooking Channel — we’re not bankrupt, we’re not struggling, we’re fine!”

However, court documents obtained by E! News tell a different story. On Jan. 25, Eustace filed an affidavit claiming McDermott had not paid eight instalments of spousal support since July 1, 2016.

“[McDermott] is working and lives in a 2 million dollar rental,” reads Eustace’s affidavit. “Order was entered mid-September. He stopped paying in November — also for 2 years prior he did not pay and I renegotiated in good faith moving forward. He owes me moving forward from February 1, 2017 100,800 in monthlies until July 1, 2020.”

In a new exclusive interview with 24 Hours, Eustace wanted to make one thing clear, “I was not livid,” she clarified.

“That is not true. When I picked up the paper and read about their latest spend, I laughed. I don’t know who their source was, but I’m so used to this. Dean and Tori’s baby shower had nothing to do with my filing. That I did weeks before, ” she continued.

On March 7, Eustace will face her ex-husband in court for the non-paid spousal support, where Eustace will represent herself.
