Hilary Duff, 24, revealed the birth of her son, Lucas Cruz Comrie via Twitter with the message, "Welcome to the World Luca Cruz Comrie! Tuesday evening, we became proud parents of a healthy 7 pound 6 ounce beautiful boy."
She later tweeted, “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.”
Back in August 2011, the former Disney star announced her pregnancy adding that she and Comrie were ready to start a new chapter in their lives.
“People keep saying to me, 'Sleep right now. Get your sleep. I keep saying, 'I just want the baby here! I want to play and I'm ready to see what he looks like,” Duff told Us Weekly in December.
She told Eonline.com, "I'm not the first person in Hollywood to have a baby. Other people have found a way to deal with it and I think I will, too," on raising a child in the public eye.
Duff and Comrie married in 2010.
