American actress shared the first picture of her baby girl with husband Gian Luca Passi de Preposulo on Sunday.
The 'Molly's Game' star took to her official Instagram handle to share her daughter picture, "You've got good taste, kid," she wrote along the post.
In the post, the star is wearing a white robe and showing off her Piaget red spinel and diamond ring while her baby can be seen reaching for the sizable stone, US Magazine reported.
Earlier, on Golden Globe red carpet, Chastain and Missi Pyle were asked about their newborn baby and social-media habit during. The 41-year-old went on to say, "I don't post anything too personal (on social media) because I'm very private about my personal life."
Chastain is a two-time Oscar nominee and five-time Globes nominee.
