Graham has yet to share her baby boy's name. She announced on her ninth wedding anniversary in August that she was expecting a child with Ervin.

"Today, we are feeling so blessed, grateful and excited to celebrate with our GROWING FAMILY! Happy anniversary, @mrjustinervin," Graham wrote on Instagram. "Life is about to get even better."

Graham said on The Ellen DeGeneres Show in November that she was expecting a baby boy.

"I'm going to be a mommy to a boy!" she shared.

In December, Graham appeared on the cover of Vogue amid her pregnancy. Graham's cover shows her wearing a gold dress and cradling her baby bump.

"This is an honor," she said on Good Morning America. "This is the future. It's about diversity and inclusion."

Graham is known for her modeling work with Lane Bryant, Levis and Addition Elle. She is the first plus-size model to appear on the cover of the Sports Illustrated swimsuit issue.
