The video clip begins with 1-year-old daughter Luna Simone looking at her mama’s belly.
“Luna, what’s in here?” Teigen asks off-camera.
Little Luna points and says, “Baby!”
Teigen, who recently celebrated her fourth wedding anniversary with musician John Legend, captioned the video with some of her signature sarcasm: "It's John's."
“Maury will have the final word on this,” Legend humorously replied in the comments.
Congratulations are in order for the celebrity couple who were public about struggling to get pregnant before Luna, and weren’t shy about speaking up against mom-shamers.
Remember how Teigen got trolled for craving Fruity Pebbles when she was pregnant? We’re sure she won’t sugar coat things the second time around either. Pop some popcorn.
