Congratulations are in order for Marisa Miller and husband Griffin Guess! 

The good-looking couple welcomed their second child, son Grayson Lee Bazyl Guess, on Friday, E! News confirms. The wee one, who joins 2-and-a-half year old big brother Gavin Lee, weighed in at 8 lbs.,14 oz., and measured 21 inches long. 

"My son Grayson is healthy and such a sweet baby. I feel so blessed and excited to see both my boys grow up together," Miller said to People. "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."

Additionally, the 36-year-old supermodel took to Instagram today to debut the first photo of her bundle of joy, simply captioning the gorgeous pic, "Grayson Lee."
