Congratulations are in order for Marisa Miller and Griffin Guess.

The former Victoria’s Secret model, 36, and her record producer husband welcomed their second child – son Grayson Lee – she announced via Instagram Monday.

The model mom confirmed the happy news with PEOPLE. Her second son arrived on Friday, May 29 in Santa Cruz, Calif.

Born at 11:23 p.m., son Grayson Lee Bazyl Guess weighed 8 lbs., 14 oz., and measured 21 inches long.

The newborn joins big brother Gavin Lee, 2.

“My son Grayson is healthy and such a sweet baby. I feel so blessed and excited to see both my boys grow up together,” the proud mom tells the mag.

She adds: “I felt very prepared for labor this time around. I was a little anxious as to when it would happen though. Having a toddler at home, you have more to organize to make sure everything is taken care of while you’re gone at the hospital.”

Miller admits the labor was “so intense and the hardest thing I’ve ever done in my life.”

She goes on to reveal that their son was born in the caul, meaning his face and head were completely enclosed in the amniotic sac.

“In honor of such a cool thing, we gave him the second middle name Bazyl, which means Kingly,” she shares. “The veiled birth’s meaning is coined as ‘Kings by right,’ so we felt it was a perfect opportunity to make his name reflect a cool story like this. And yes, that is a dimple on that baby’s smiling face!”

Congratulations to the Miller-Guess family!
