She's less than a week old, but Luna Simone Stephens is already a hit on social media.

Chrissy Teigen and John Legend welcomed their daughter to the family last Thursday, and on Tuesday night, the new mom shared the first photo of her with the rest of the world.

The sweet Instagram post not only shows Teigen cradling Luna in her arms — while Teigen's other baby, pup Pippa, looks on — but it also reveals Luna's not-so-surprising nickname.

"Hi my Lulu!" Teigen wrote in the caption.

As for the star of the pic, she's looking up at mom, so her face can't be seen. But what we can see is adorable — including her full head of hair.

Little Lulu's new fans agree. Almost 23,000 comments now accompany the post, and there's no shortage of the word "cute" among them.
