She's finally here!

Hilary Duff and boyfriend Matthew Koma have welcomed a baby girl named Banks Violet to the world, they announced on Instagram yesterday.

"Banks Violet Bair this little bit has fully stolen our hearts! She joined our world at home on Thursday afternoon and is absolute magic,” the actress captioned a pic of them and their new princess.

"Banks Violet Bair /// 10.25.18 /// We welcome a beautiful daughter, little sister, and best friend for life. Could not possibly be more grateful for our growing family and for the 🍊 who makes it all possible. Cloud ten," the proud dad wrote on his own page.

The Younger star, 31, also shares son Luca Cruz, 6, with her ex-husband Mike Comrie.

Duff and Koma have been dating since early 2017, and announced in June that they were expecting a baby together.

Congrats Lizzie Maguire!
