"She’s here!" Teigen shared on social media, alongside a photo of Luna and Miles gazing at their new sibling. "The house is bustling and our family could not be happier."
The "Cravings" author said that other women have shared their own pregnancy loss experiences with her after going public with her story.
"I would be lying if I said this did not majorly suck," says Teigen, who lost son Jack last year.
Teigen says she feels "lost" after fallout over her past bullying of Courtney Stodden.
The former 'GMB' host called Teigen 'a despicable piece of work who built a career around being married to a pop star'.
Courtney Stodden claimed Chrissy Teigen sent them direct messages urging them to take their own life.
"The platform no longer serves me as positively as it does negatively, so with that I bid you adieu," Chrissy Teigen wrote on Instagram.
Fans says the revealing photo is "normalizing daily motherhood" — and the lack of privacy that comes with it.
The model shared a photo of herself to Instagram, showing that she still had a bump months after suffering a miscarriage.
Chrissy Teigen and John Legend have given their first interview since their pregnancy loss.
