Dean McDermott is airing his dirty laundry.
In a new clip from the Lifetime reality series "True Tori," the actor explains his reasoning for allowing himself to cheat on his wife, Tori Spelling.
When a friend asks him why he jeopardized his relationship to have a very public affair with Emily Goodhand, Dean says that his addiction to drugs and alcohol led him down the wrong path.
"I didn't think that I would get caught," Dean admits. "I was drinking and using drugs. I was not dealing with things that happened to me in the past. It's not like I was looking for sex -- our relationship and sex life is solid."
"I have a brain that wants to kill me. I have a brain that wants me dead," he continues.
The couple is working to salvage their turbulent marriage, but the stress may have landed Spelling in the hospital.
According to E! News, the "Mystery Girls" actress recently was released after spending six days in the hospital ... and cameras filmed the whole thing.
