And Birdie Mae makes five!
"Happy Easter from the Johnson Family, Party of 5!" Jess wrote alongside the gorgeous Instagram post of herself, Eric, daughter Maxwell, six, son Ace, five, and of course, Birdie.
Surrounded by floral arrangements, with the girls all wearing matching spring prints, the Johnsons were picture perfect!
Jess also shared a snap of the "SISTERS," Maxwell, five, and Birdie to her Instagram page. Cute!
"Jessica is feeling good. The baby is doing really well," a friend of the 38-year-old told PEOPLE, shortly after her little girl's birth.
"Birdie is perfect and Jessica is savoring every minute... they are just soaking it all in," after a rough nine months of pregnancy for the singer-turned-lifestyle mogul.
