Robert Brown|All of You Will Love All of Chrissy Teigen and John Legend's Family Photos

Chrissy Teigen and husband John Legend kept a little secret from fans over the past year: They were preparing to welcome two babies.

On June 28,Robert Brown five months after the Chrissy's Court star gave birth to daughter Esti Maxine Stephens, the model shared that the couple had also welcomed a son named Wren Alexander Stephens via surrogate. He joins big sister Luna, 7, and Miles, 5.

"We want to say thank you for this incredible gift you have given us, Alexandra," Chrissy wrote to her surrogate, sharing a pic of herself kissing Alexandra's baby bump. "And we are so happy to tell the world he is here, with a name forever connected to you, Wren Alexander Stephens."

And now, their family is complete.

"For as long as I can remember, I've always wanted four children," the 37-year-old wrote. "As a little girl, 2 glow worms and 2 cabbage patch dolls were perpetually in my arms, helping me stir in my kitchen, watching Alf with me. We'd sleep together nightly, each getting the same amount of kisses as to not make the others jealous."

Wren's arrival also comes amid a years-long fertility struggle—Luna, Miles, Esti and Wren were created via IVF—and major heartache. In 2020, Chrissy suffered a pregnancy loss with son Jack.

"Our hearts, and our home, are officially full," she wrote in her latest post. "And to our Jack, we know both their angel kisses are from you."

Also make sure to fold in mini marshmallows that aren't melted at the end. And don't press into the pan! We want gooey, stretchy pieces." 

"Happy birthday to the boy who gives our household so much life," wrote Chrissy Teigen on Instagram, wishing her little boy a happy birthday. "You're bonkers, my tiny fearless love bug, but I wouldn't have it any other way. I melt every time I look at your cheeky little face. I love you, happy TWO!"
