Hilary Duff and Matthew Koma have become parents to their first child, a baby girl.

They have named the little one Banks Violet Bair, whom Duff, 31, gave birth to last Thursday at her residence.

"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 "Younger" star wrote alongside a photograph with her boyfriend and the baby.

She also has a six-year-old son, Luca Comrie with former husband Mike Comrie.

Koma, 31, also shared the same picture a while later expressing his excitement.

"... 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 musician wrote.

They had announced pregnancy in June.

Duff and Koma have been dating since last January.
