Congratulations are in order for Chrissy Teigen and John Legend. The couple are expecting their second child, reports People. On Tuesday (Nov. 21), Teigen announced her second pregnancy on Snapchat by showing off her baby bump in a mirror selfie.

“Very excited to not have to hide this anymore. Everyone I told first was like ‘uh yeah we knew thanks,’” she wrote in the caption of the photo featuring herself wearing a strapless black dress.

Teigen then went on her Instagram page and shared a video of their 19-month-old daughter Luna Simone pointing to her belly. “Luna, what’s in here?” the mom-to-be asked her daughter. You then hear Luna proclaim, “Baby!”

Luna was conceived through in vitro fertilization where they chose the sex of the baby, which resulted in the pregnancy of their daughter.

The sex of the couple’s second child hasn’t been revealed but it’s expected to be a boy. Teigen has previously said on Twitter, “Since this is coming up again, I said our next baby would be a boy because that is the embryo we have left. A boy. So. Yeah.”

There's no word as of yet on when the baby is expected to arrive.
