John Legend and Chrissy Teigen’s youngest kid has just turned one year old!

The iconic singer, 45, took to Instagram on Saturday to commemorate the milestone event for his family of six, pouring his heart out for his youngest daughter, Esti Maxine.

“Esti Maxine is ONE today!” Legend said in the caption to the wonderful birthday post. “She’s been lighting up the house since day one,” he said, adding many red heart emojis as well.

The accompanying carousel article displayed a variety of heartwarming photos of the child throughout her first year of life.

One of the photos showed the baby kissing her own reflection, while another showed her testing out her legs while standing up with the help of various objects about the house.

Another photo showed the tiny girl channelling her model mother, looking glamorous in red-tinted heart-shaped spectacles and a pink bib, while another showed her cradled in her adoring father’s embrace.

The 12-time Grammy winner also tweeted a photo from the birthday celebrations, which showed the birthday girl next to a cake nearly as big as her.

Perched on the counter, she smiled broadly for the cameras as her loved ones surrounding her.

Last January, Teigen announced Esti Maxine’s arrival.

In addition to Esti Maxine, the couple has a seven-year-old daughter Luna Simone and two sons, Miles Theodore, five, and Wren Alexander, six months.
