Johnson and Simpson had announced that they were expecting again on Instagram back in August.
"This little baby girl will make us a family of five," she said of the time. "We couldn't be happier to announce this precious blessing of life."
Simpson announced that she planned on naming her daughter Birdie with an extravagant baby shower back in January.
Throughout her third pregnancy, the designer had a series of health woes. In addition to suffering from incredibly swollen feet and sciatica pain, the star was also hospitalised with bronchitis four times in two months. Not only that, but there was also that time that she literally broke a toilet seat.
