“Birdie Mae Johnson. 3.19.19. 10 Pounds 13 Ounces,” she captioned her Instagram announcement.
The exciting news comes just two days after the singer, 38, shared a photo of her bare baby bump in a bikini on Instagram. “Jess-tation,” she captioned the pic.
Simpson and Johnson, 39, are also parents of daughter Maxwell, 6, and son Ace, 5. The Dukes of Hazzard star announced in September that the couple were expanding their family.
“SURPRISE…” she captioned a photo of her two kids holding giant black balloons on September 18. In a second post, the fashion designer shared a pic of Maxwell and Ace surrounded by pink balloons.
“This little baby girl will make us a family of five,” Simpson wrote. “We couldn’t be happier to announce this precious blessing of life.”
An insider told Us exclusively that she and Johnson were “surprised but overjoyed” about having a third baby.
“Jessica and Eric are over the moon. They are so happy and very excited,” the insider told Us in September. “It’s fun because Ace and Maxwell are at an age where they understand what is happening. They are really cute waiting for their baby sister.”
“Being a mother is the best opportunity and challenge I’ve ever been blessed with in life,” she told Us in May 2018. “Right now my kids are in this amazing stage where I’m really listening to them without judgment and they’re teaching me so much. These little innocent kids teach me so much about life.”
