According this article, Birkhead received 1.7 million dollars for those Birkhead & Baby pictures printed in OK magazine when he was first reunited with the baby. If someone offered you 1.7 million dollars for pics of you and your kid would you do it? I would... in a heartbeat : )
I personally don't think there was anything wrong with the OK Magazine pictures. I did however, think it was distasteful do have ET filming the babies visit to the grave and that whole saga.
