The Johnsons' new baby, whose name and gender have not been revealed, joins their sons Gibson, 11 months, and Jennings, 2, and Ricki, Maynard Johnson's 12-year-old daughter from her relationship with the late Ricky Hendrick.
Johnson shared a sweet snap of Ricki holding the baby for the first time.
He also shared a clip of Maynard Johnson relaxing with the baby in her hospital bed.
Maynard Johnson posted a photo of her "hospital camp out" supplies: a cake and a bottle of Veuve Clicquot rosé.
She may be a married mother of four, but that rosé proves she'll always be the Bachelorette.
