Here is what I think.
Nicole and Tom splitting shocked everyone. The biggest shock was that Nicole was shocked. I remember her interviews, saying she really doesn't know what happened. I was sad for her. Nothing like thinking you are living a fairytale, and he walks out.
Then, a few weeks later, another shock! Now Tom is incedibly cruel. Nicole was pregnant, and she had a miscarriage. It all made sense to me then. Because, I had remembered an interview with Mimi Rogers years ago, I remember it well, because of thinking how awful it was to give out that information. But one of the things she said was Tom was the reason they could not have kids. He was infertile. I will never forget it, because I thought, no matter how nasty your divorce is, to spill that, was just wrong.
Tom=infertile, maybe Nicole did not know this, and Nicole=pregnant. Well, Nicole, Tom found out a very bad thing you did, because the baby couldn't be his. No wonder she was shocked.
I am very leery about this so called "baby" Katie had. It would be very easy for them to have an adoption process going on, time it to a delivery date, hide the "baby" from the public until the real baby is in their custody.
Either way, I don't care what anyone says, there is no way that baby is Tom's. Funny, 2 wives, no kids with the 1st wife, adoption with the 2nd wife, LEAVES a pregnant wife, and all of a sudden, after only weeks of dating, Katie Holmes is pregnant..after him declaring his undying love for her, something he had never done with any of his other leading ladies.
Nothing adds up. Except for maybe the changing sizes of Katies belly over the nine months, that seemed more like 10.5 months, considering in October, they announced she was 4 months pregnant.
