Spelling and McDermott have weathered ups and downs since first tying the knot in 2006, including McDermott's infidelity. Back in 2021, Spelling revealed in an interview with SiriusXM's "Jeff Lewis Live" that she and her husband were no longer sleeping in the same bed.

"Right now, my kids and dogs sleep in my bed," she said at the time. Spelling elaborated that the couple stopped sharing a bed after he was away for six months while filming an unnamed project. 

"Since he left — this is not good, you guys — but since he left, he was gone for six months filming in another country, they all stayed with me," Spelling said. "So, I currently still have four in the bedroom with me who have yet to go back to their rooms."

"They have beds in there and two sleep in bed with me,” she added. "And pets. Three dogs.”

McDermott told the Daily Mail last year that his longtime substance abuse issues were among the factors that contributed to the breakdown of their marriage, with Spelling spending more time with their kids as a result.

"I just isolated more and more and more and she isolated with the kids. We were roommates. Rarely did we eat together. We'd sit down and have a family meal but it was always disjointed," he said. "It made me feel worse because I knew I was a big part of (the problem) and I was at a place where I felt there was nothing I could do about it.

"The relationship suffers greatly," he said. "When you're in a roommate situation and there's no connection or intimacy, what do you expect is going to happen?"

"I've never been so lonely in the same house with six other people, never been so lonely in my life," he said. "I didn't know how to get out of the situation I was in. I was hurting. I was heartbroken. I was depressed. I hated myself. I didn't want to live."

In the interview, he also blamed "Hollywood" and his mother-in-law, Candy Spelling, as contributing factors in the dissolving of their marriage. But McDermott still took some accountability.

"It's going to be living the rest of my life making amends because I took something that was really beautiful and I just tore it down year after year, day after day," he said.
