Who is Really the Father of Katie Holmes Baby?

According to a post on ONTD, "I was listening to the radio this morning and tuned in mid-discussion to the morning DJs at my favorite station talking about Katie Homes' "pregnancy". Apparently they had talked to a reporter from The Insider that morning and had come to the conclusion that Katie was really pregnant by Chris Klein before she and Tom got together, but that Tom said that he was OK with raising the baby as his if she would play wife to him. They also concluded that she has already had the baby (evidenced by the loss of pregnancy weight around her face and ankles recently, and the fact that not many fathers would be as far away from a ready-to-pop mother as Tom is from Katie), and that she is wearing a prosthetic belly in order to both promote Tom's new movie best and to make the timeline right so that it looks like it really is Tom's and not Chris' (evidenced by the ever changing size/shape of Katie's belly)."

"I know there have been discussions around here about Katie's belly being fake and even if she was ever pregnant at all, but I never remember hearing the Chris Klein theory."
