Michelle Branch is welcoming the newest addition to her family! On Friday, the singer took to Instagram to reveal that her third child has arrived— and it's a girl!

Branch shares photo and name of new baby girl

Branch posted a precious photo of her brand-new daughter, who is wrapped in a floral blanket. "Welcome to the world, sweet Willie girl," Branch wrote, before explaining where the little one's moniker came from. As it turns out, the inspiration for her name came from both Branch's family and her husband Patrick Carney's!

She revealed that Willie was born on February 2, saying she is "named after Patrick’s grandmother Willie Madge and has my mother’s maiden name/my middle name." Branch gushed about how she and Carney are "so in love" with their little girl, adding an emoji of a blushing face surrounded by hearts.

Carney also made his own post announcing his daughter's arrival, saying that Willie was born at "7 pounds 5 ounces and 18 FEET HEIGHT." The couple already share 3-year-old son Rhys, while Branch and her ex Teddy Landau have 16-year-old daughter, Owen.
