Ryan Gallagher and Tracey Jewell tell WHO they were both totally blindsided by the emotional affair playing out being closed doors between Dean, 39, and Davina, 26.
"I felt stupid," says Ryan, 29, who watched his onscreen wife express her dissatisfaction with their marriage and openly embrace and make commitments to another man. "I didn't know anyone could hate someone so much, just for being themselves."
Equally blindsided, Tracey, 34, says not only did Dean convince her their marriage would last, but they made love on the same night he told Davina he'd leave his TV wife for her.
"I had no idea about Davina, none, zero," says the mother-of-one. "I was absolutely shocked and humiliated, I couldn't believe someone could do that to me."
