As we all know by know, Last Monday Night on Raw Miz and Maryse announced that they are going to have a baby. With Miz and Maryse announcing their pregnancy, it appears that barely anyone in WWE actually knew they were expecting or that they would be making it public and announcing it on the show. 
The Miz and Maryse cleared the announcement with a few key people, while pretty much everyone else in the back was taken by surprise.
