Nicole, who has just had a second child with Keith via a surrogate, said she wouldn't have gotten married if she thought there could be a divorce, like what happened when she split with Tom Cruise.
She said, 'I'm married now to the person who, you know, 'til death do us part.
'I wouldn't have gotten married again if I didn't feel like that was the case with us.
'And unless some hideously terrible thing happened, that's what we have both pledged to each other, and there's a great deal of comfort in that.'
Nicole, 43, refused to speak to the mag about Isabella and Connor, the children she adopted with Tom Cruise, and who chose to stay with him after their split.
'Yeah, but it's their life, and it's not to be discussed publicly.
'I've never discussed any of that publicly.
'Except to say that I absolutely love them.'
