I'm more than sure Mariah is expecting and keeping it under wraps literally. Kudos to her for doing so. So many celebs spit their business as soon as they concieve.

Someone who I follow on Twitter and works in the entertainment industry in the US was at Nick Cannon's birthday party last week and said that Mariah is definitely pregnant, because her stomach is seriously swollen and didn't drink alcohol the whole night.

She's wearing a lot more black and wearing looser fitting clothes in that area. Plus a few months ago she stayed home/away from the spotlight for weeks on end recording in her studio and wasn't seen until her show in Brazil after last being seen with Nick visitng their doctor.
