Paging Mariah...

The cast likes to think about what life would be like for a swing in Pregnancy Pact.  With a score like this, you've got to be a musical savant who has a three or four octave range who can hold tight 6-part harmonies.  Experience with babies preferred.  Acting experience optional.  Age unimportant.

So who can it be?  Besides a unicorn.  There is only one...  (After the jump, obviously.)

She was good in Precious, right?
