All these pictures show Mariah at her heaviest.She has gained weight all over her body,in the face and the belly area.But there are other clues too..Mariah saying the Brazil concert was tough for her for personal reasons..Showing up at the airport wearing a maternity dress..And then it's Nick..In the past,when asked about Mariah being pregnant,he would quickly discard the rumours.Not this time..During his short talk with Perez, he acknowldged the weight gain and basically confirmed the rumours by saying that a pregnancy is a personal matter for a woman and that Mariah will speak when she wants to,when she feels it's safe..
I have no doubt in my mind now that she is indeed pregnant and that at this stage they are basically being protective of the whole situation..
