LONDON: Her desire to have a child has been no secret.
But despite her joy at finally being able to share her pregnancy news, Mariah Carey has been surprisingly open about the realities of having a baby.
'Right now I feel nauseous, I'm exhausted,' the singer admitted to husband Nick Cannon on his radio show this morning.
And the 41-year-old says she has stayed 'insulated' from the outside world since breaking the pregnancy news.
'I didn't even look and see who contacted me,' said Mariah.
But Nick, 30, is determined that this Christmas is going to be the best one yet for the happy couple.
He says that this year's festivities will be even 'bigger' than before because the couple has 'lots to celebrate', something his wife agrees with wholeheartedly.
'Yes, we do,' says Mariah. 'We definitely, most certainly do.'
Mariah is busy promoting her new Merry Christmas II You album but says she will soon take a break.
'I guess after New Year's,' she said.
Nick writes on his website: 'My wife and I keep our personal business very private. Being under a microscope 24/7 is not easy, so it is very important to keep certain things between just us.
'Mariah revealed the news about her miscarriage and the long road of healing it took to try and move forward.'
The second part of Mariah's three part interview with access Hollywood is airing tonight at 7.30pm.
The couple have already spoken about the 'dark time' they went through in 2008.
They revealed they were about to fly out to meet family and friends in Colorado when a last-minute doctors appointment found Mariah had suffered a miscarriage.
The actor says his wife managed a brave face in front of friends and family.
Nick says: 'Even though it was emotional for both of us, that's when I really saw the strength in this woman right here. She just handled it so well.
'And then to get on a plane and have to spend Christmas with friends and family, and no one knew. I felt like everybody was kind of speculating.'
Earlier, Mariah ended months of speculation by saying: 'Yes, we are pregnant. This is true.
'Itís been a long journey. Itís been tough because Iíve been trying to hold on to a shred of privacy.'
