Somewhere, Jessica Simpson is bellowing "Dang it, I'm so jealous, I need this critter off my hee-haw!"
Expressing her joy through Twitter, Hilary - who married former ice hockey player Mike Comrie in 2010 - said: '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."
Hilary, who is a young mum by today's standards being 24, was thrilled when she found out she was pregnant and admitted she couldn't wait to meet her son.
She said: "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'."
Give her 4 weeks and the priority between sleeping and playing might shift just slightly.
