Mariah Carey knows we all want to know if she’s pregnant or not, so what does she do? Wear a dress that looks like a maternity gown. May as well ride the publicity wave as long as possible. Mariah Carey is São Paulo, Brazil preparing for a performance Saturday, August 21 at the 55th Barretos Rodeo. I guess we will have to wait and see what outfit she wears during her performance.
