39-year-old model Molly Sims and her husband Scott Stuber welcomed their first child on Tuesday.
A representative for Sims revealed that the baby weighed just over 7 pounds.
The proud new parents have not yet revealed their son's name, but an insider told People Magazine of the couple: "They both couldn't be happier."
Sims told Us Weekly last month of preparing for the new baby:
"We did our first birthing class the other day," she said. "I swear to god I thought he was going to faint!"
She added of her son's nursery: "It's kind of bohemian, modern chic. We have made it so cool. I'm so happy. It's my favorite room!"
She also revealed to People: "I am a little nervous about the delivery and breastfeeding."I hope I can do it, I hope we come through. I am so excited to meet him and just hold his hand."
