Hilary Duff is a mom!
But obviously you only care about one thing (besides the good health of mother and child, that is): What's his name?!
"Welcome to the World Luca Cruz Comrie!" Duff tweeted, noting that he arrived "healthy" and "beautiful," weighing 7 pounds, 6 ounces.
"We are overjoyed...He is surrounded by so much love!! Mom and baby are both doing extremely well."
Duff, 24, and Comrie, 31, tied the knot in August 2010.
Congrats to the brand-new family of three!
