Tori Spelling has not publicly addressed recent allegations that Dean McDermott cheated on her, but insiders claim the actress firmly believes her husband was unfaithful.

Emily Goodhand, 28, reportedly told Us Weekly that she had an alcohol-fueled sexual encounter with McDermott, 47, on Dec. 6 after meeting him at a group dinner. The infidelity happened while McDermott was in Toronto to promote his new hosting gig on Chopped: Canada.

Spelling, 40, is rumored to believe the claims.

"She is refusing to comment on the cheating rumors publicly, even though she believes Dean cheated on her," sources told Radar Online. "Tori is obsessed with having a picture perfect family, and thinks it a big part of her image. Commenting or addressing the cheating would taint that image."

McDermott allegedly slipped Goodhand his hotel room number the night they met and the two had sex. Goodhand claimed that McDermott gushed about his wife, but told her they had a "sexless" marriage.

"He said, 'I love my wife. I love her so much. But she won't sleep with me," the model claimed.

McDermott expressed love for his wife in the past. He sent her a video on her birthday earlier in 2013 apologizing for having to be work all day, but telling her he loved her several times.

Spelling admitted in the past that she is particularly sensitive to the possibility of McDermott cheating on her, especially considering their history. They had an affair while on the set of the 2006 movie Mind Over Murder, and later divorced their individual spouses at the time to be together. They married that same year.

"If the phone rings and it's a girl's voice, I have to ask if he's having an affair. Dean tells me over and over again that he would never do that," she wrote in her 2010 book Uncharted TerriTORI.

Spelling told friends she had a "deep, dark feeling" McDermott would cheat on her, different sources said. One explained, "She has never completely trusted him and has always kept very close tabs on Dean. But despite all that, Dean still cheated."

The couple has also reportedly been slammed with reports of McDermott being unfaithful before, as well as allegations that they've secretly separated several times in their seven-year marriage.

"Tori and Dean have already separated three times, right after she gave birth each time, " a source told Hollywood Life back in 2012.

Tori Spelling and Dean McDermott Fighting Behind Closed Doors?

Spelling joked about her fourth pregnancy with son Finn happening so quickly after the birth of the couple's daughter Hattie saying she feared McDermott would seek a better sex life than a mother-of-three could provide.

"I was like, 'Well, I don't want him to think that the sex is going downhill,' " she said at the time.

Spelling has yet to publicly comment on the infidelity claims and has instead focused on sharing joyous photos of her family.

"I can't believe Christmas is already over. We had such a fun day hanging at home unwrapping presents, eating homemade goodies and watching movies. SO grateful for my family!" Spelling wrote on her blog Dec. 27.
