Baby Luna rocks curly pigtails in denim jacket and orange dress in new pic

Chrissy Teigen and John Legend's little daughter Luna looked like the ultimate sweetheart as she headed out dressed in an orange polkadotted dress and a denim jacket.

Since the arrival of her brother, Luna has been trying to adjust to the fact that she is not the only child in the house anymore. During her mother's interview with Today, she says that while Luna knows something is going on, she doesn't quite understand it.

"She sees that something is going on, but I don't think she's getting it."

While the Legend family has finally welcomed Miles Theodore Stephens into their lives, Chrissy has still been sharing photos of her eldest child Luna on her Instagram more frequently.

The TV host decided to dress her daughter in an orange polkadotted dress which she accented with a light blue denim jacket and a pair of white sneakers. All dolled up as her curly hair was tied up in pigtails, Luna posed against the wall and smiled adorably for the camera.

In the first ever photo of the two siblings together, Luna seems to have gotten used to having her little brother around. In the shot, Luna, 2, takes care of her little brother Miles, who is just over a week old.

It seems Luna has been trying to get used to her new role as the big sister, trying to do simple responsibilities such as watching over his furry crib and feeding him a pacifier as he sleeps.

On May 17, Teigen announced that she had given birth to a healthy baby boy, her second child and first son with husband John Legend. Three days later, she shared a photograph of her son to the world in an adorable close-up.

"Hello, world! This is Miles Theodore Stephens - We are drowning in his little peeps and nuzzles. Our household feels overwhelmed with love. Thank you for all your well wishes!"

During her interview with Today while she was pregnant with Miles, Chrissy shares that she and John are hoping to have more children in the future.

"I hope [we have a lot of kids] but it's expensive to live in New York."

Chrissy and John met while filming the music video for his song "Stereo" in 2007, and have dated ever since. In 2011, Legend proposed to Teigen during a Christmas trip to the Maldives. With their busy schedules, the two only got married two years after, in a destination wedding in Lake Como, Italy, the place where they first met. Since then, the couple welcomed their first child Luna Simone Stephens on April 14, 2016, and now, Miles Theodore Stephens last May 17.
