As they say: “Once a cheater, always a cheater.” At least that seems to be the case for Dean McDermott, Tori Spelling’s husband of seven years, as it’s now being reported that he cheated on the Beverly Hills, 90210 actress with a much younger woman.

In an interview with Us Weekly, the other woman, 28-year-old Emily Goodhand, shares that she met the 47-year-old while he was promoting his gig as host of Chopped Canada in Toronto earlier this month. The two reportedly met through friends, after which Dean invited Emily to his room at the Fairmont Royal York Hotel where they had sex.

"He told me he and Tori had a sexless marriage," she claims, adding that the two spent the night together the following day, as well. "I believed him."

Though reps for Tori, 40,  and Dean have yet to comment, all seemed well in Tori’s tweet yesterday (December 25), wishing fans a Merry Christmas from the whole family — including Dean.

“As another year comes to a close, I can’t help but feel so grateful for all of my blessings,” she writes below a precious photo of her four young children. “My beautiful family, my amazing friends, and of course, all of you! We’re spending the day together — cuddling, cooking, baking, unwrapping gifts, eating, watching movies and counting our blessings… How are you spending Christmas Day? Love, T, Dean, Liam, Stella, Hattie + Finn.”

Should this report be confirmed as true, it might not come as a complete shock for fans of the reality couple. Tori has been very open about her fear that Dean would become unfaithful, even discussing it in her book unchartered terriTORI. Much of this has to do with the fact that the couple got together under precarious circumstances: both Tori and Dean were married to other people at the start of their relationship.

“I’m a girl, I worry about that stuff,” she’s said. “Do I technically really think he’s going to cheat on me? No … He’s a good-looking man, in the business we’re in. He’s got a lot of fans, women fans. So, you know, I always think about it.”

We wish the best for the couple and their family at this difficult time.
