Chrissy Teigen revealed the gender of her knew baby on Instagram last night following the Grammy Awards. In an adorable post, Teigen shared a photo of herself in her Grammy’s dress cradling her bump with the caption, “Mama and her baby boy.”

She and husband John Legend are expecting a son! Luna, who turns 2 in April, is getting a little brother. Teigen used Luna to share the news that she was pregnant. The Instagram video featured the toddler talking to her mom's belly and repeatedly saying baby.

Although this is the first time the model has very publicly shared the news she is pregnant with a son, it is not the first time she has mentioned the gender. It is common knowledge she and Legend used IVF to conceive both of their children. Teigen was part of a social media discussion about IVF where the topic of gender was discussed.

In this somewhat tense conversation, Teigen was blasted by users for her choice. She took this as an opportunity to explain her struggle and it was during this conversation it slipped that her next baby would be a boy.

"Hi Linda, thanks for asking, you complete witch. I tried for about 9 years. Anything else, let me know!" she said. However, the conversation was far from over and Teigen felt the need to explain herself even more.

Teigen continued, “Since this is coming up again, I said our next baby would be a boy because that is the embryo we have left. A boy. So. Yeah."

Interestingly enough, this exchange took place before John Legend’s wife was actually pregnant for the second time. It is only since she publicly revealed the gender of her baby that fans are recalling this previous conversation.

Both Teigen and Legend have been open about their struggle to conceive a child. They have praised IVF for giving them the family they always wanted. Not forcing opinions or answers, they have both openly shared what worked for their family. Though the couple has come under fire for their choice, they have remained a positive inspiration to many couples that have had fertility issues.

John Legend and Chrissy Teigen are expecting their baby boy early this spring.
