Hilary Duff has welcomed a daughter with boyfriend Matt Koma. The little girl has a unique name and is absolutely adorable.

The proud parents each used social media to share the good news that Banks Violet Blair joined their family last Thursday. Both Duff and Koma used the same photo of their baby girl but shared different messages. They shared Banks' birthday and a sweet note to the little one.

Other than the fact that she was born last Thursday at home, no other details such as time of birth, weight, height, etc. have been shared at this time. Perhaps there are individual pieces of information the couple wants to keep to themselves.

She is less than one week old, but Banks is becoming quite the social media sensation thanks to all the photos her famous mom has posted on Instagram. The star began to flood her Instagram stories with shots of the little girl once the official announcement was posted. Fans have been freaking out over all the adorable pictures, thanks, Hilary.

Banks is already one stylish lady. Even though she is swaddled in all of the photos, she, of course, has the cutest swaddle blankets on the market. One of the cutest shots is of the baby sleeping all swaddled up with her hands near her face. She is all scrunched up, and it is seriously too cute for words. The last picture was courtesy of Banks' dad who also wasted no time showing off his bundle of joy on social media.

Hilary Duff is also mom to 6-year-old son Luca, with her ex-husband Michael Corrine. She is also not shy about sharing pictures of her boy and expressing how happy she is to be his mother. Here is hoping fans get to see a photo of Luca with his new baby sister very soon.

The 31-year-old and her beau have been dating for a couple of years. They announced last June they were expecting their first child together, even sharing it was a girl.

Congrats to Hilary Duff, Matt Koma and Luca on the addition of beautiful baby Banks to your family. What do you think of the name Banks Violet? Let us know your thoughts in the comments!
