Ashlee Simpson and husband Evan Ross are now the proud parents of beautiful baby girl, Jagger Snow Ross.
The bundle of joy was born on Thursday and is the first for the newlyweds.
Prior to releasing the baby's name, a source told People: "Ashlee is doing amazing and their daughter is perfect."
This is the 30-year-old singer's second little one as she also has six-year-old son, Bronx, from her previous marriage with Fall Out Boy member Pete Wentz.
The arrival of their newest addition comes as the happy parents are set celebrate their one year wedding anniversary next month. Ashlee and Evan tied the knot in a romantic cermony at his mother Diana Ross' Connecticut estate on August 30th, 2014.
