Chrissy Teigenis revealing howher pregnancy losswas a “transformative” experience for her — and how “in a way, it really saved” her.

On Monday’s episode of her daytime talk show,Ellen DeGenerescalls the 35-year-old model and cookbook author “super brave” for sharing the “raw” photos from the hospital after she and husbandJohn Legendlosttheir son Jack at 20 weeks gestationback in late September.

And for Teigen four months later, “Looking at those pictures now, it seems like so long ago. And also, of course, everything was such a blur,” she says. “Even thinking back to it now, I amstill in therapy about it andI’m still coming to terms with it.”

“I have maternity clothes, and there are things that I bought for my eighth month and my ninth month,” the star continues. “So it’s just hard because he would’ve been born this week, so you look at those things and you have these constant reminders.”

At the same time, Teigen (whorelaunched her Cravings websitetoday) thinks it’s “really helpful” that she was “raised in a household that was very open about loss,” as it helps her reflect on how it “can be a beautiful thing.”

“It was a really transformative thing for me and in a way it really saved me, because I don’t thinkthat I would’ve discovered therapy andthen sobriety and this path of feeling good about myself and feeling like a new person,” she tells DeGeneres, 63.

TheLip Sync Battlehost also explains how her sonMiles Theodore, 2½, and daughterLuna Simone, 4½, are keeping their brother’s memory alive in the family’s daily life.

“Of course,” Teigen says of the loss, “you don’t ever imagine it happening to you — I think that was the crazy part for me is, ‘I hear these stories about other people. This kind of stuff doesn’t happen to me.’ So when it does, you’re just so shocked.”

“And thenyou think about all the people that go through itin silence and you get really sad for them. Ours was so public, so so many people were so supportive,” she adds. “You really gain this incredible amount of empathy. And I really, somehow, think I’m a better person now. And I just have the best support system ever.”

For theChrissy’s Courtstar, she was “perplexed” when it happened and tells DeGeneres of the harrowing experience: “You really don’t know the meaning of the word ‘unimaginable’ until something like that happens to you.”

“And then afterwards, there’s such a spiral of things you could’ve done differently and you start to get really tough on yourself,” Teigen says. “But what you learn through it about yourself is such a wild, incredible thing, and this week,we’re thinking about [Jack]especially.”
