The 30-year-old model and her husband, John Legend, 37, welcomed Luna Simone Stephens last week and proud mother Teigen has taken to Instagram to share a sweet picture of herself with the tot.
Teigen's picture shows her cradling the tot and is captioned: "hi my lulu!"
The couple announced the birth over the weekend, with Teigen writing on Instagram: "She's here! Luna Simone Stephens, we are so in love with you! And sleepy. Very sleepy."
And John tweeted: "Our new love is here! Luna Simone Stephens, born on Thursday, the 14th. We couldn't be happier!"
The tot weighed 6lbs 11oz, according to Teigen's Instagram post.
Teigen previously revealed she chose a female embryo while undergoing fertility treatment.
She said: "I've made this decision. Not only am I having a girl, but I picked the girl from her little embryo. I picked her and was like, 'Let's put in the girl.'
