Mariah Carey and Nick Cannon are not only expecting twins, but they’re having both a boy and a girl, they revealed to Life & Style.

“There were fan contests on Twitter about what gender they are and rumors about them being two boys or two girls, but nobody guessed this,” Carey tells the magazine.

The news is convenient, given how Carey has been preparing for the babies’ homecoming.

“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,” she says.
