The speculation over whether Mariah Carey is pregnant or not is now over, according to Radar Online. Sources tell the website that the singer and husband Nick Cannon are officially expecting. “They’re both very excited and very happy,” the source says. “Mariah and Nick want to keep the pregnancy quiet as long as they can.” The desire for secrecy could explain why during a road-trip up the Malibu coast over the weekend, Carey opted to not get out of the car when photographers were around.
