John Legend reveals the personal struggle that brought him and Chrissy Teigen closer

John Legend and Chrissy Teigen found strength in their struggles, he told Cosmopolitan.

"Having a baby is a big challenge for a couple, and going through that together strengthens your bond because if you make it through [having a child], you know you can make it through anything," Legend explained.

Legend, 38, told the publication that rather than allow their struggle to conceive naturally come between them, he and Teigen remain focused on the positives.

"You want to feel like everything's working properly and want everything to be perfect, but sometimes it's not. I wouldn't say we can't conceive naturally, but I would say that it's enough of a challenge where it felt like we needed help," Legend shared."We're lucky that we're living in an age where we can conceive in other ways. [In vitro fertilization] brought us Luna and hopefully it will bring us a few more awesome kids, too."
