The sweet video brought joy to many other people as well, with a fan supportively commenting, "What a wonderful moment and joy! I’m so glad you finally have the complete family you worked so hard for! Enjoy it all!"

"That smile!!! How can you ever say no to that lil smile?!" said another.

Many couldn't help but note how similar Wren looks to both his father and his older brother, 5-year-old Miles. "Awww looks like a tiny miles ??????," said one, while a different fan wrote, "Johns twin to the tee!"

Quite a few also commented that Teigen's newborn looks like her mother, Vilailuck "Pepper" Teigen, especially when he smiles.

At the end of June, Teigen and Legend shocked everyone when they announced that they secretly welcomed their fourth baby, Wren, via surrogate, just over five months after their daughter Esti was born. Along with the two new babies and Miles, the couple also shares a 7-year-old daughter named Luna.

Now, the 37-year-old and her husband are enjoying their full life as a family of six, often sharing sweet moments, like Wren's first smile, with the world on social media.
