The former Victoria's Secret Angel and her husband Griffin Guess - who already have two-year-old son Gavin Lee together - welcomed their new baby into the world on Friday (29.05.15) in Santa Cruz, California.

The couple have named the tot Grayson Lee Bazyl Guess, and he weighed in at a healthy 8 lbs.,14 oz.

Marisa has revealed her labour was "intense" but she felt more prepared after giving birth once before.

Speaking to PEOPLE, she said: "It was so intense and the hardest thing I've ever done in my life. I felt very prepared for labour this time around ... I had such an amazing support system at the hospital and my family, I felt totally taken care of."

Expressing her joy with her new arrival, Marisa - who tied the knot with Griffin in 2006 - added: "I feel so blessed and excited to see both my boys grow up together. My son Grayson is healthy and such a sweet baby. I was a little anxious as to when it would happen though. Having a toddler at home, you have more to organise to make sure everything is taken care of while you're gone at the hospital."

Marisa also revealed Grayson was born in a caul, which is a harmless piece of membrane which covers the baby's face and head, something that only occurs in 1 in 80,000 births.

And Grayson's special arrival into the world inspired the name she and her spouse gave him.

She revealed: "In honour of such a cool thing, we gave him the second middle name Bazyl, which means Kingly ... 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."
