Is Tori Spelling regretting her decision to air all her dirty laundry on True Tori yet? While in the midst of dealing with McDermott's infidelity, her own hospitalization, and her mom Candy Spelling's tell-all book; she now has to deal with accusations from McDermott's scorned ex-wife - that Dean was addicted to cocaine.

Dean McDermott Cheating Scandal 'Creepy'

Mary Jo Eustace, McDermott's first wife -- whom he famously dumped for Spelling -- has allegedly made accusations of McDermott's cocaine use. Radar Online reported on May 12 that they exclusively obtained court documents previously accusing McDermott "of cocaine use, out-of-control spending, anger issues and even brutally beating his own dog!"

McDermott started an affair with Spelling while both partners were still married. They met on a television movie shoot in 2005, after which McDermott infamously dumped Eustace. Now, somehow, we are seeing Eustace's 2005's sworn court declaration:

Read selections from Mary Jo Eustace's shocking allegations:

First, Cocaine:

"In March 1999, I went to my parents for a family gathering with Jack [her son with McDermott, who was an infant at the time.]"

McDermott "missed the gathering because he didn't feel well. During the course of the event, Dean McDermott walked into the living room, threw a bag of cocaine on the table and said, 'I have a cocaine problem.'

"[Dean] started crying uncontrollably and was shaking and said that he should go to the emergency room," she claimed. "I was able to calm Dean McDermott down. Dean McDermott told me he had used cocaine when he was in the house alone with Jack.

"I called a friend who had a cocaine addiction, who helped Dean McDermott get into a support group," she continued. "Dean McDermott committed to the support group and controlling his addiction to cocaine ... for a while.

"As a result of my knowledge and experience in connection with Dean McDermott's prior use of cocaine, alcohol and anti-depressants/prescription drug medication," Eustace said, "I believe Dean McDermott is medicating himself without the supervision of a doctor and that this is one of the recent causes of his recent erratic behavior."

Second, Tax and Money Problems:

Eustace's declaration reveals that she had to manage the money because McDermott's spending could not be controlled.

 "During our marriage, I have been required to control our finances as a result of Dean McDermott's serious impulsive spending issues and lack of responsibility in connection with payment of taxes and other financial commitments."

Third, Parenting Problems:

"There are many examples of Dean McDermott's lack of patience in parenting Jack which I will set forth in further detail at a later time."

Finally, Anger Management... and that Dog Beating:

"I noted [his] awful temper. We had a lunch date, and afterwards went to his house in Toronto to feed his dog. The dog had gotten into the garbage. Dean McDermott repeatedly and violently beat the dog with his fists and with a rolled up magazine. Dean McDermott was furious and it was very intimidating incident for me to witness."

After 12 years of marriage, Eustace and McDermott filed for divorce on March 13, 2006. McDermott, who was having an affair with Spelling at the time, married her a few weeks later on May 7, 2006. Eustace and McDermott share joint custody of their son Jack.
