Report: Mariah Carey and Nick Cannon Expecting a Boy and a GirlMariah Carey and Nick Cannon are already looking forward to double duty with the upcoming birth of their twins, but the couple are now happily revealing that they're getting the best of both worlds and expecting both a boy and a girl.

The pair, who married in 2008, announced Carey's pregnancy in October 2010, although it wasn't until December that news that the pair were expecting twins was made public.

Now Carey tells 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!"
