Now that's one hot mama -- supermodel Marisa Miller has given birth to her first child, a boy!

According to People, Marisa and her music producer husband Griffin Guess welcomed son Gavin Lee Guess on Thursday in Santa Cruz, Calif.

“I’m completely overjoyed by the birth of our son," Marisa told the magazine.

"I feel so blessed to be a mom and am so excited to experience this next part of life.”

The little guy entered the world at 7:58 p.m., weighing 8 lbs., 10 oz. and measuring 22¼ inches long. He is the first child for Marisa, 34, and Griffin, 33, who have been married since 2006.

The former Victoria's Secret Angel recently bared more than normal for a spread in Allure, proudly showing off her baby belly in all its glory.

Congratulations to the family!
