Chrissy and John, who married in 2013, are expecting their second child through in vitro fertilization, a process they've publicly detailed.

It was their 21- month-old daughter Luna, who announced her mother's second pregnancy to the public in a heartwarming video Chrissy posted to Instagram this past November.

“Luna, what's in here?' said the mother-of-two-to-be, referring to her stomach, and her firstborn replied: 'Baby.'

Since Legend picked the name of their first born  daughter Luna - Teigen will choose the moniker of their next baby, who could be a girl if her Instagram post is anything to go by. She posted a photo with her bare baby bump and captioned it “girl’s weekend” which could hint that it is a baby girl they are expecting.

The brunette beauty, who last year revealed she has given up drinking, has been open about suffering postpartum depression after Luna's birth.

Writing in Glamour last year, she confided: 'I still don’t really like to say: "I have postpartum depression," because the word depression scares a lot of people.

'I often just call it “postpartum.” Maybe I should say it, though. Maybe it will lessen the stigma a bit,'

We really hope that this time round she will not go through postpartum depression.
