The 33-year-old actress and singer shared a photo of Mae James, her one-week-old daughter with Matthew Koma, Wednesday on Instagram.
The black and white picture shows Mae lying on her back and looking at the camera. Next to her is a card with information including her name and birth date.
"Most people post this on the first day..... but you're a 3rd child Mae Mae .... soooo it's happening on the 7th... happy week earth side little bit! We love you so...." Duff captioned the post.
Duff also has a 2-year-old daughter, Banks Violet, with Koma, and a 9-year-old son, Luca Cruz, with her ex-husband, Mike Comrie. She announced Mae's birth last week with a photo of Banks in a bathtub.
"I'm a big sister ....... marinating on how I feel about that!" Duff wrote.
