She tells chat show host Ellen DeGeneres, "It's basically my husband takes me through sort of a meditation. So he's, like, saying, 'You're relaxed and you're floating on clouds while you're going through labour and your contractions.'

"He just sort of does a guided mediation. I'm just concentrating on breathing and staying relaxed because it's when you get tense that makes the whole labour worse and more painful.

"I actually did this with Honor... It is kind of a way to relax and know that the contraction will only last for so long. You just need to concentrate on the breathing and just the sound of his voice... Normally I want to strangle him but at that moment it's sort of calming and wonderful."
