After announcing her pregnancy in August 2011, we have watched Hilary’s bump grow as she went to pilates class, shopped and town, and even stepped out on the red carpet. The wait is finally over.

“Welcome to the World Luca Cruz Comrie! Tuesday evening, we became proud parents of a healthy 7 pound 6 ounce beautiful boy,” Duff wrote. But the 140 characters weren’t enough to express her joy, so Duff kept tweeting. She continued: “We are overjoyed and feel like the luckiest parents in the world…He is surrounded by so much love!! Both mom and baby are doing extremely well.”

Hilary continues to keep her fans posted on everything Luca, using Twitter to give thanks to well-wishers and discuss feeding times.

We can’t wait to see the first photos of little Luca! Congratulations Hilary and Mike!
