Tori Spelling and Dean McDermott's romance got off to an inauspicious start when they cheated on their spouses with each other before tying the knot (more on that later). Dean, however, didn't learn from his past and in 2013, a woman named Emily Goodhand revealed she'd had a sexual encounter with the reality star, who later admitted to cheating on wife Tori. "I'm like, 'No, I'm not a monster, I'm a human being and I messed up.' I'm owning up to it and I'm getting help," he said. "But to label me a monster or evil is very hurtful. The affair was more about how I was feeling about myself than having an affair." Tori forgave him and they're still married to this day.
