Dean McDermott Blames His Cheating on Alcohol and Drug Abuse

Well, so much for the bad sex excuse.

In a new preview clip for True Tori, a Lifetime reality show essentially based on the decay of Tori Spelling and Dean McDermott’s marriage, cheating spouse McDermott is blaming his infidelity on everything but himself again. The actor, who cheated on first wife Mary Jo Eustace with Spelling in 2006, says drugs and alcohol clouded his judgement and led him to sleeping with a 28-year-old he met in Canada.

“I didn’t think that I would get caught. I was drinking and using drugs, man,” he tells a friend in a sneak peek for an upcoming episode. “I was not dealing with things that happened to me in the past.”

“It’s not like I was looking for sex, or I was horny,” he explains. “I have a brain that wants me dead.”

Previously, McDermott, 47, slammed his wife’s bedroom skills, saying that he had only slept with Emily Goodhand because he wasn’t getting enough attention in the sack from Spelling.

“We would have sex once every two weeks,” he said. “It wasn’t fantastic.”

After news of the affair broke, McDermott admitted himself into rehab for “intense treatment.” As for Spelling, who’s rumored to be addicted to pain killers, she was recently hospitalized for at least six days amidst the couple’s therapy to deal with their marital problems.

As they say, the sTORI story continues.
