Dominic Monaghan refuses to discuss his personal life in public because once he does, there is no turning back.

Speaking to British TV presenter Jonathan Ross last night, Monaghan refused to confirm he is dating his Lost co-star Evangeline Lily.

And the actor claimed he never will discuss his personal relationships. He said, "So much of my life is for show. The choices that you have is what you keep private and what I keep private is, strangely enough, my private life."
