The actress and her husband Mike Comrie welcomed a son on Tuesday, March 20, Duff Tweets.
"Welcome to the World Luca Cruz Comrie! Tuesday evening, we became proud parents of a healthy 7 pound 6 ounce beautiful boy," she writes.
"We are overjoyed and feel like the luckiest parents in the world," she continues. "He is surrounded by so much love!! Mom and baby are both doing extremely well."
Duff, 24, announced in August that she was expecting her first child, saying that she and Comrie were "ready to start this new chapter in our lives." And she described the experience of being pregnant as "kind of like a little alien has taken over your body. You just don’t quite feel normal." Nevertheless, she said her pregnancy was "super easy."
In November, Duff flaunted her growing belly on the red carpet, where she said she'd decided to forego loose fitting outfits and to show off her changing figure. "I'm kind of like, 'Well, it's there, and everyone knows it's there,' so I think it looks better to wear tighter clothes."
Over Christmas, the star even embellished her bare belly with a picture of a gift and wished fans happy holidays "from the three of us."
Duff and Comrie – who got married on August 10, 2010 – can now look forward to many happy holidays as a family.
