The singer/actress, who rose to fame in Disney's "Lizzie McGuire" series, and her husband, Mike Comrie, welcomed a son Tuesday night. They named the boy Luca Cruz Comrie.
Hilary posted the happy news on her website Thursday afternoon:
"Welcome to the World Luca Cruz Comrie Tuesday evening, we became proud parents of a healthy 7 pound 6 ounce beautiful boy. We are overjoyed and feel like the luckiest parents in the world. He is surrounded by so much love!! Mom and baby are both doing extremely well."
It's the first child for Hilary, 24 and Mike, 31. Mike recently retired from the NHL. Hilary added they are "overjoyed" by their new addition.
Even Mike seemed overwhelmed by becoming a father.
Welcome to the World Luca Cruz Comrie! Can't express my feelings for you right now.
