Tori Spelling and Dean McDermott's marriage woes don't really give ex-wife much happiness as Mary Jo Eustace said that it's horrible for the children.

A new clip for "True Tori" reality show, per Radar Online, shows how Mary Jo Eustace feels amid all the talks about woes on Tori Spelling and Dean McDermott's marriage and she's not too happy about it.

The two talked over dinner after eight years of not seeing each other. In the clip, Tori Spelling confesses about her husband's cheating ways as she tells Dean McDermott's ex-wife, "You can say I told you so."

Dean McDermott's ex-wife Mary Jo Eustace replies, "I don't hate Dean. I mean, he's a total knob. I know that. But he's your knob now."

But she said that she's not getting any satisfaction from the problems Tori Spelling and Dean McDermott's marriage is facing. "It's actually really horrible," Eustace said, particularly for the four children who are surely affected by all the tension.

Dean McDermott cheated with Mary Jo Eustace with Tori Spelling, who was then also married to another man. They left both their spouses and had four children together.

Mary Jo Eustace tells Tori Spelling that she felt humiliated and in shock when she heard about the cheating, noting that "We were real people, and a real family."

Tori Spelling then asks that if she hadn't entered the picture, would her Mary Jo Eustace's marriage to Dean McDermott would have endured. She responded in the negative as she notes, "Then there would've been somebody else."

In an earlier interview, Dean McDermott told E! News that he really thought that Tori Spelling would divorce him immediately right after the reports of his cheating ways were splashed on the tabloids.

"I wake up every morning and I'm just so blessed that she's in my life still. [Tori]'s such a strong lady, and when this happened I was like, 'Why don't you just leave me?'" he said. "And she's like, 'Well, I love you, I can't just turn that off. I'm mad at you, I'm really upset, I'm really hurt - but I love you. That just doesn't go away.'" he added.
