Dean McDermott has been accused of cheating on his wife Tori Spelling. A woman named Emily Goodhand tells Us Magazine that McDermott cheated on Spelling by having one-night stand with her earlier this month.

Goodhand says that she met McDermott on December 6 through mutual friends at Pravda Vodka House in Toronto. The group of eight people later moved to a bar at the Fairmount Royal York Hotel. Goodhand then claims that she and McDermott had a chat while drinking.

"I was drinking so what he said is blurry. But he was talking about his kids and his work. And when people open up, you feel closer to them in some way. I felt like I could trust him. And we know a lot of the same people, so we had that in common," she tells the magazine, adding that McDermott secretly slipped his room key.

Goodhand met him in his room after the friends left and they allegedly had protected sex. "He said, 'I love my wife. I love her so much, but she won't sleep with me.' I didn't ask why because it was awkward," Goodhand recalls their conversation.

According to Goodhand, McDermott showed stills from his sex tape with Spelling during their second meeting. They ordered room service and cuddled, but did not have sex. She and McDermott separated after he got back to L.A.

Goodhand now regrets her action and apologizes to Spelling. "I'm an adult and I make my own decisions. I'm sorry. I f**ked up," she says. McDermott and Spelling have not responded to the cheating claim.
