Everyone knows and loves Chrissy Teigen as the beautiful model and of course, mother to John Legend's child. We also love her sassy Twitter jokes and how real she is with her fans on social media. The only thing she's really kept private, and we can understand why, is her journey with IVF treatments. For years, the celebrity couple has struggled to conceive naturally and even when undergoing IVF treatments. After finally having their baby girl Luna, John Legend thanks IVF for making the option of having a baby a possibility. He encourages hopeful parents with fertility issues to try the procedure for themselves. Teigen says she appreciates all the support and encouraging words that have poured in after they've shared their journey.
