The mom-of-two's handsome hubby could barely contain his emotions as the "Love Me Now" singer flooded the comments section with numerous heart-eyed emojis.
The longtime lovebirds tied the knot in 2013 and share two children, Luna, 6, and Miles, 4. Legend and Teigen have been candidly open about the loss of their unborn son, Jack, who didn't make it after Teigen had an emergency "life-saving abortion" in September 2020.
Teigen has been overjoyed to bring fans along throughout the journey of her rainbow baby pregnancy and has continuously received loads of support beneath every updated progression picture.

"Girl! No stretch marks???? What sort of witchcraft???" asked a third fan, as others began to play a guessing game of the gender of Teigen's child.
"You look amazing! Do you know what you’re having or will it be a surprise? My guess is a boy ❤️," wrote one user, as another disagreed, stating, "Definitely a girl ❤️."

"No offense but why do you need to display yourself and obviously John doesn’t care! Just asking. Not heard of in my time!" one user harshly judged the star, as another chimed in and questioned, "Don’t you want to keep ANYTHING private?"

"Storks illustrated? I don’t know," Teigen joked of her play on words, as her supportive husband commented, '"Storks Illustrated' is some of your best work. 😍."
