Last month, Teigen announced she’s pregnant with her second baby.
A source close to the family told ET at the time that Teigen is pregnant with a boy, and that she and Legend are thrilled to be welcoming another child.
"Chrissy and John are so excited to be having another baby -- and Luna is too!" the source said, adding that it hasn't been easy with Teigen's past struggles with infertility and postpartum depression. "She loves touching Chrissy's belly and 'talking' to the baby."
