Teigen's mom Vilailuck posted a snapshot of the 37-year-old singer kissing the 30-year-old model's baby bump on Instagram, writing, "Home!" with heart-eyes emojis.
Legend and Teigen married in 2013 and announced the model's pregnancy in October. The couple went shopping for baby clothes Sunday with Kanye West and Kim Kardashian, who shared a first photo of their 2-month-old son Saint the next day.
"So today we went baby shopping with @johnlegend & @chrissyteigen. Kanye & North were a little too quiet. We found them passed out in the middle of the store," Kardashian wrote of her husband and 2-year-old daughter, North.
Teigen faced backlash last week after telling Us Weekly she will hire a night nurse for her daughter, who is due in the spring. The model responded to the criticism by clarifying the nurse's role in a tweet Saturday.
"I am so used to sharing our life that I forget how protective I will be soon. I cannot handle this kind of constant judgement!" she wrote. "A night nurse doesn't replace you waking and feeding at night. You're up with them. They're helpers and teachers."
Teigen previously told InStyle Australia Kardashian advised her to "go stretchy" with her maternity clothes. The model showed off her baby bump in a fitted white gown at the Grammy Awards last Monday.
