Congratulations are in order, as Hilary Duff has given birth to her third child!

Duff first acknowledged her growing family with an Instagram post on Friday, March 26. The post featured a photo of her daughter Banks, 2, in the bath tub.
"I'm a big sister ……. marinating on how I feel about that," she captioned it.
In a subsequent post made on Saturday, March 27, Duff shared an intimate, black and white photo of her growing family. In the photo, Duff is at home, in a birthing tub, with her new baby and Banks. Husband Matthew Koma and son Luca, 9, admire the newborn from outside the tub, with Koma's hand lovingly in his wife's hair. Koma appropriately wore a hat with "GIRL" written on it in large letters.
"Mae James Bair- We LOVE you beauty 3-24-21," Duff wrote of her new addition. Mae's last name, Bair, is Koma's actual last name; Koma is his stage name. Duff's post also gave credit to her birth photographer, Lauren Guilford, and Birthing Rhythm, a midwifery team.
She subsequently posted two Instagram stories of Mae as well, one showing off the back of her head and shoulder rolls, captioned "Mae Mae," and one of her tiny newborn feet. Koma shared two of the photos as well.
This was a big week for the "Younger" star. In addition to welcoming Mae, her children's book "My Little Brave Girl" was also released.
