Chrissy Teigen and John Legend’s youngest baby Wren is sunshine personified. He just celebrated his first birthday in new photos, and his ever-present smile and model-worthy hair will just melt your heart!

“Our Juneteenth baby with the big smile and beautiful curls, Wren Alexander, is 1 today!” Legend wrote on Instagram on Wednesday. Teigen showed some love commenting, “happiest boy 🥰🥰🥰.”

In the first photo, Wren sits in a baby swing outside. He’s grinning and showing off two tiny teeth on top and two on bottom. His squishy little cheeks as he smiles are just perfect! In another picture, Wren laughs in his crib as his older brother Miles, 6, reaches out to touch his forehead. There are also photos of him in a swimsuit with his mom, in his highchair covered in food, and outside dressed in little overalls and a hat. With his adorable curly hair and happy face, Wren seriously couldn’t be cuter!

The Chrissy & Dave Dine Out star, who also shares daughters Luna, 8, and Esti, 17 months, with Legend, posted a series of sweet photos of her baby boy last month. “Wren’s pure joy appreciation post 🤍🩷🤍🩷🤍” she captioned the carousel on Instagram. It included snaps of Wren giving sticky smiles to the camera during dinner time, playing with a soccer ball, and crawling around the grass in the backyard.

In March, Teigen shared a precious photo of Wren after a bath. He’s lying on the carpet in pajamas with his hair slicked back. “Big boy got that hair conditioned hooooo baby,” the Cravings author captioned the photo. Legend commented, “An actual doll.”

Happy birthday, Wren! We can’t wait to see the joy you bring over the next year.
