Tori Spelling suspects husband Dean McDermott may have had an Ashley Madison account and recently confronted him about it.

Sources tell Radar Online with the couple already rumored to be going through financial difficulties, "Tori began poring over previous credit card statements looking for proof" that her husband had an account with the married dating service.

While she didn't find anything linking him to the service, Spelling has yet to completely drop the issue, even though her husband turned over his laptop to her so she could check.

"He understood why Tori was questioning him," added a source. "But after six hours, they were still fighting about it! Dean has had enough of Tori's doubts and questions."

Elevating stress levels all the more for the couple has to be news of ongoing money woes. The family recently downsized to a smaller home and to save money rented a U-Haul trailer instead of hiring a high-priced moving company.

"They are still living in a beautiful home," said a source. "Just by Tori Spelling's and her father Aaron's standards, it's obviously far more limited than the past extravagant homes."

In addition, McDermott's ex-wife Mary Jo Eustace recently charged he is several months behind on child support payments owed to his teenage son.

"Dean hasn't been paying Mary Jo what he owes," said a source. "She's really upset and wants him to pay up."

At the time of his death in 2006, Spelling's father, legendary TV producer Aaron Spelling, was estimated to be worth as much as $600 million. He is known for producing working such shows as "Dynasty," "Sunset Beach," "Charmed," "Seventh Heaven" and "90210 Beverly Hills," which Tori starred on as Donna Martin for several seasons.
