However, the 32-year-old, who stars in police drama 'Lewis' tuned in when he grew suspicious she was enjoying filming antics such as bondage, threesomes and sploshing - when lovers cover each other in food.
"Billie didn't want me to watch it. But I started thinking to myself, 'Why is she always saying all this and why am I not watching it?" the Sun quoted him as saying. "Is there something bad here? Are you enjoying yourself, Bill?' So I watched it and I was really impressed. We never think of sploshing in our private time. We're actually boring like that," he added.
