In an effort to get past McDermott's affair with Emily Goodhand, Tori Spelling met with Mary Jo Eustace. However, instead of getting closure, Spelling grew further concerned after reading an old love note between McDermott and Eustace.

"I walk in, and Dean has everything in order," Spelling told the camera, according to a Nov. 10 sneak peek by E! News. "He's made dinner for the kids, their homework is done and there's a beautiful bouquet of flowers with a card. It's a love note from Dean to me, and I just read this love note from Dean to Mary Jo. Oh my god how ironic is this."

Dean McDermott Quits 'True Tori,' Reveals Suicide Plot

Spelling went on to claim Eustace informed her that things between her and McDermott were going well, prior to McDermott cheating on her, and that she had no reason to believe he'd cheat.

"It's a lie…I don't know what to tell you, babe," McDermott said in response to his ex's claims. "The whole thing about having her on the show too—the more she comes across is as this wonderful, loving person, people are watching going like 'Yeah what the f--k is Dean's problem?' I gave her a great life…she's f--king crazy. She's f--king delusional."

In 2005, while Spelling was married to playwright Charlie Shanian and McDermott was married to Eustace, the pair began an affair. In May 2006, after divorcing their previous partners, Spelling and McDermott were married. In 2010, they renewed their vows.

While things between McDermott and his ex-wife are clearly not very civil, things between him and Spelling appear to be going well. On Saturday, the pair stepped out in Los Angeles, as reported by Us Weekly, where they were seen running errands and holding hands.

True Tori airs on Tuesday nights at 9 p.m. on Lifetime.
