Gospel singer is set to welcome her firstborn child any time now.

But her journey to motherhood was not easy. In a past interview with Kiss FM's Chito Ndlovu, Kambua spoke extensively about her marriage.

Chito asked her, "Many peoples marriages are under attack, young people are beginning to feel like I don't need to get married because there is a lot of stuff going on. How are you protecting your marriage?"

Kambua said, "Uhmm you know I don't know how people do it without God, or and I'm not trying to super spiritualize this, but when you think of two people coming from two very different world, trying to merge and create one world, honestly it takes God to make it work. So, uhhmm yeah, six years into it so far so good, and I think that just learning to be friends with the person that you are married to, uhmm because you know that all that fluffly, lovey dovey feeling it kind of just."

She continued,

'..after you have kind of just, you're in each others face, you're not always feeling like oh my God..you're heart is not always like you know! but uhmm he's my friend, and I love to hang out with him, I love to spend time with him, so being friends with the person that you are married to and having God as a foundation'. 

Kambua and the hubby have been subjects of many blog posts and social media commentary, more so because of their age difference.

Chito asked Kambua if her hubby reads all the blogs, that refer to him as an ancestor and their marriage?

One of the things I'm really grateful for is that I met a really strong man, and it's because of him being strong that has helped me in my ministry, in my career, that he is not phased or moved by what people say, and for the moments where I've gone through things and felt ..ok..this has really hurt me, he has been there to speak life to me and to encourage me so you know,...how he feels about honestly.

She added, "If there's anyone who is not bothered, it's my husband and I'm learning, he is teaching me how to do that, how to not care because either way, regardless of what you do, people will always have an opinion. It just comes with the territory, so yeah, he is cool."
