John Legend is ''fine'' with Chrissy Teigen opening up about their fertility problems.

The stunning model spoke of her struggles to get pregnant on new talk show 'The FABLife' with Tyra Banks earlier this month and she insists her singer spouse has no issue with the candid discussion.

She told 'Entertainment Tonight': ''He was, of course, so happy. He's fine talking about it. We've been open about it to absolutely everybody in our life. All of our friends have known for years now.

''It would've been odd for me not to talk about it on the show because it's been such a huge part of our life. I've been doing this for years. It's been weird to hide it from people, but I didn't want to just tweet, 'Doin' my shots again!' ''

Speaking about the fertility issues on 'FABLife', Chrissy, 29, says she would have had ''four or five'' kids with the 'All of Me' hitmaker by now if not for the troubles.

She said: ''John and I were having trouble. We would have had kids five, six years ago if it had happened. But my gosh, it's been a process.''

''Every single time I sit down for an interview with anybody ... I will say, just being two years into being married, the questions just come from all over.

''It's kind of crazy because I can't imagine being that nosy to be like, 'So, when are the kids coming?' because who knows what somebody's going through.''

Chrissy also tweeted: ''It makes me really happy that by @tyrabanks and I sharing our stories and struggles, a lot of you feel like you can do the same and not feel ashamed!''
