Shouldn't the big question be, "Who the hell is the father ?" Assuming he has ever had sex with a female, it is widely believed he is sterile.
But, Lord Almighty, what the hell was Katie thinking ?
That was almost exactly what I said to my husband - "Aw, isn't that cute. Tom's gonna perform his own ultrasounds on that baby Katie got from somewhere."
Re your question on who is the father.
You've heard it here first. Put your tin-foil hat on but be prepared for it to be true. I think Ron Hubbard probably had some sperm frozen before he died and Katie Holmes has been impregnated with it. We have some Rosemary's Baby action going on. If that baby has red hair - you know I'm right!
