Tori Spelling and Dean McDermott are reportedly fighting again. According to a report from Radar Online, the actress is worried that her husband is part of the recently leaked Ashley Madison accounts leak.

The couple made news last year after Tori Spelling discovered that Dean McDermott was having an affair. Their ordeal was documented in their family's reality series "True Tori," which also features their four young children.

Now that they are trying to rebuild their marriage, Tori Spelling is afraid that Dean McDermott is among those who will be exposed for having an Ashley Madison account. The said website is notorious for promoting extramarital affairs.

"As soon as it became news that the Ashley Madison website had been hacked, and that users' names were being released, Tori got into a vicious fight with Dean," an insider revealed.

"Convinced Dean had an account on the site, Tori began poring over previous credit card statements looking for proof."

The insider added that Tori Spelling's paranoia over Dean McDermott having an Ashley Madison account is completely understandable.

"He understood why Tori was questioning him," the insider said.

"But after six hours, they were still fighting about it! Dean has had enough of Tori's doubts and questions, and has declared there was never any involvement with the website."

Prior to the Ashley Madison issue, Tori Spelling and Dean McDermott shared how they might soon renew their wedding vows to show a united front. According to a report from Life and Style, the cheating scandal that rocked their marriage last year seemed to have made them stronger.

"I would love to renew our vows," Dean McDermott revealed. "When the time is right, we'll do it."

OK! Magazine also recently reported that Tori Spelling and Dean McDermott's financial problems are causing a strain on their marriage. The "Beverly Hills 90210" teen star allegedly cannot seem to give up the rich lifestyle she grew up with as the daughter of Hollywood producer Aaron Spelling.

"Dean's been trying to get the family back on track, but Tori just refuses to quit her pampering ways," said a source. "For Tori, Mommy's needs come first."
