The supermodel also made another joke about her thigh-baring AMAs dress.
Baby Luna will soon be ready to eat her mother's cooking.
Chrissy Teigen and John Legend both shared an adorable photo of their 7-month-old daughter wearing a "Little Legend" onesie while posing with the family bulldog, Puddy. The 30-year-old supermodel's mother, Vilailuck, commented on the photo of her granddaughter, writing: "I got one tooth now."

Luna's first tooth comes after her mom posted about her baby girl's "first savory bite," and the same week as Teigen made headlines for the thigh-baring -- to say the least -- dress she wore to Sunday's American Music Awards.
After jokingly apologizing on Monday "to anyone harmed mentally or physically by my hooha," Teigen shared a Family Guy meme that she compared to her AMAs outfit. "'Hey baby. Do those legs go all the way up?'" she quoted. "Dead. Thank you @qween.memes #familyguy #spongebobsquarebodinaworldofbooty."
Teigen also clapped back at some of her critics during a Thanksgiving-themed Twitter Q&A on Wednesday. When a commenter named Alivia pointed out that she “could’ve just worn pants” to the event, the Sports Illustrated swimsuit model responded, "Well, Alivia, hindsight is 20/20. Just like your mom when she named you with an ‘A’ instead of an ‘O.’ ”
