Chrissy Teigen, John Legend welcome fourth child Wren via surrogate

Chrissy Teigen finally has the four kids she'd always dreamed of.

Teigen revealed she and husband John Legend welcomed their fourth child via surrogate, she wrote in an Instagram post Wednesday. Their newborn son Wren was born "just minutes before midnight" on June 19, Teigen said.

In her Instagram post, Teigen talked about her journey working with a surrogate following the loss of her baby, Jack, at 20 weeks of pregnancy in 2020.

"For as long as I can remember, I've always wanted four children," the model wrote. "As a little girl, 2 glow worms and 2 cabbage patch dolls were perpetually in my arms, helping me stir in my pretend kitchen."

"After losing Jack, I didn't think I'd be able to carry any more babies on my own," she continued. "To be honest, I've personally blocked out a lot of my mindset during that time, but one clear memory is being surrounded by people who wanted to make sure I wouldn't go through that pain and loss again."

Teigen said she and her husband then reached out to a surrogacy agency in 2021, looking for two tandem surrogates to help carry their third and fourth children.

"At some point, early in our surrogacy journey, I came out of a therapy session, walked downstairs and said to John — I want to try to carry just one more time," Teigen shared of her change of heart.

That decision led Teigen to go through IVF again, giving birth to baby Esti Maxine Stephens earlier this year.

"Around this same time, we also met the most incredible, loving, compassionate surrogate we could ever imagine, Alexandra," Teigen said. "I knew she was a perfect match for us the moment we spoke to her.

"The first embryo we tried with Alex didn't survive, and I will never forget how hard she fought to get ready for a second transfer," the model said. "As we crept toward the safe zone of my own pregnancy, we were overjoyed to learn Alexandra had become pregnant with a little boy. Our little boy.

"We ate hot pot to celebrate, watched Vanderpump Rules with our growing bellies, our families blending into one for the past year," Teigen wrote. "Just minutes before midnight on June 19th, I got to witness the most beautiful woman, my friend, our surrogate, give birth amidst a bit of chaos, but with strength and pure joy and love."

Teigen also shared adorable photos of new baby Wren at the end of her post, as well as a photo with their surrogate Alexandra, "forever connected" to the baby, whose full name is Wren Alexander Stephens.

"Our hearts, and our home, are officially full. And to our Jack, we know both their angel kisses are from you," Teigen wrote, concluding the post.
