According to Extra, the 42-year-old booked a caesarean section to guarantee that she gives birth.
An insider claimed: "Hollywood baby bump watchers are whispering that the singer is scheduled to undergo a C-section at an L.A. area hospital on Friday."
Although the couple are yet to comment on the speculation, Cannon discussed the impending birth on The Talk yesterday.
The presenter admitted that Carey is ready to give birth, explaining: "How's [Mariah] doing? She's pregnant. She's doing amazing, but literally, it's any moment now. It's not even any day now… She is ready to just pop!
"The baby nurse and all that is ready. [The] bags are packed! I don't know why I'm here!"
Cannon added that Carey nearly went to the hospital on Wednesday as she thought she was going into labour.
