Presenter Molly Sims delivered her first child on Tuesday.

The 39-year-old stunning star and first-time mother welcomed a baby boy with her husband Scott Stuber on June 19.

US Weekly magazine reports that the infant, whose name has not yet been revealed, weighed in at a healthy 7lbs.

Molly and Scott married last September and this marks their first entry into parenthood.

Molly spoke previously during the late stages of her pregnancy about the anxiety she experienced prior to giving birth.

"You get big and you get uncomfortable," Molly shared with the publication last month. "You start thinking that at any moment you might go into labour even though you know it's not true."

Molly also discussed why she and husband Scott were arguing about what to name their son.

"He wants to meet him [first]," Molly said of her husband's decision. "But I'm like, We're going to be too stressed in the hospital!' We had a little bit of an argument on that."
