It seems that 21-month-old Luna Stephens hasn’t quite gotten used to her famous parents’ hectic schedules. Chrissy Teigen and John Legend have been understandably busy as of late with awards season upon us — and poor Luna gets upset whenever they leave. “She is always sad when we leave. She throws a little fit,” John said to E! News on Saturday, Jan. 27 at Clive Davis’ annual Pre-Grammy Gala.

“But it’s also because it’s late at night and she’s just a cranky butthead at nighttime,” wife Chrissy jokingly added. “She gets tired at night so everything gets worse,” John further explained. Aww, poor Luna! Luckily for the soon-to-be parents-of-two, Luna returns to her normal, happy self fairly quickly. “As soon as the door closes, she forgets us. She’s moved on to something else,” Chrissy continued.

Chrissy and John — who spent the past few days in New York — certainly had an exciting Grammy Awards weekend, first attending the Gala and then the actual awards show on Sunday. Chrissy even took the special occasion as an opportunity to make a pretty big announcement — she’s expecting a baby boy! The model flaunted her baby bump in two gorgeous gowns over the weekend, and she truly is glowing during her second pregnancy.

The news doesn’t come as a total shock, however. Back in October, Chrissy revealed that she and John would be trying for a second child. She had previously undergone IVF treatments in order to conceive Luna, which left her with one remaining frozen embryo. And she even had already revealed the gender of the last embryo 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,” she wrote. Still, such exciting news! Little Luna is going to make the best big sister to her little brother.
