Good question

I think that celebrities and some women are just plain lazy (I'm mot coming down on people who may really need interventions if that's their belief.) They have a lot of money to hire people to give them a second opinion about such matters. They also have way more than enough money to hire a trainer and nutritionist to ensure the couple is in tip top shape to have a baby . Furthermore, I believe that once these celebrity couples agree to have children they immediately go to the doctor and the doctor will hurry up and persuade and pressure the woman into IVF or other treatments just because its a quick process that they--the doctor-- will get paid for whether by check or reputation. This type of thing is great for big business and the media to partner up and say "See your fav pop icon is going to the
hospital for having their babies and you should too." That's not good given that "We The Sheeple" is already robots to the Machine and all the crazy and bizarre diseases and disorders running rapid at the hospital these days. This particular current event is a media exercise to ease us to believing that hospitals are good for us and off-springs.
