Melbourne: Mariah Carey and her partner Nick Cannon, who are due to welcome twins in April, have revealed they are expecting a boy and a girl.
The couple was surprised that nobody had guessed their happy secret.
"Even before we announced it was twins, I was trying to keep everything gender-neutral because I didn`t want to impose an identity on them too soon,” the Daily Telegraph quoted Carey as telling Life and Style magazine.
"There were fan contests on twitter about what gender they are and rumours about them being two boys or two girls - but nobody guessed this!" the singer said.
Meanwhile, actor-and-comedian Cannon - who broke the news the couple were expecting their first children back in December - confirmed they would be having mixed gender twins.
"It`s a touchy issue because you never want to say too much too early. If my wife says it`s true, then it is," he told E! Online.
