Chrissy Teigen and John Legend are expecting a boy

This is the second child for the model and her husband, John Legend.

"mama and her baby boy," she wrote, next to a picture of her draped in a silver gown while touching her belly.

"I didn't think it could happen to me. I have a great life. I have all the help I could need. But postpartum does not discriminate," Teigen wrote in Glamour last March. "I'm speaking up now because I want people to know it can happen to anybody and I don't want people who have it to feel embarrassed or to feel alone."
