Carey expecting boy and girl
Mariah over the moon as she reveals twins' sex
In an interview with Life & Style magazine, the singer has openly spoken about her joy at finding out she is expecting a boy and a girl.
Carey said that before finding out the twins' sex she kept all her baby purchases in neutral colours, but since being told their gender she's been buying everything in blue and pink.
"There were fan contests on Twitter about what gender they are and rumours about them being two boys or two girls" said Mariah "but nobody guessed this!"
Husband Nick Cannon added that the couple won't pick "crazy names" for their children, but that they will definitely be unique.
Mariah , who is to become a mum for the first time, is due in April.
