Mariah "I'm a Diva" Carey's possible pregnancy of the day

Mariah Carey, 38 now, is buzzing!
The rumors say she might be pregnant: her fast marriage with Nick Cannon, her recent visit in Petit Tresor to discuss about nursery decors, her growing belly (ok that's not a reason)... But here's the most significant thing: She's invited at Oprah Friday!! How could THIS not be a sign? I'm saying this because everytime she got at Oprah's, she annonced ultra important infos like marriage, new album, and... butter free diet.
Oh well... Anyway, we'll know more about this on Friday.
