Prepping for the Golden Globes is usually a flurry of makeup artists, hair stylists, and couture creations, but Jessica Chastain took a break from posting about her glam squad to give her followers a glimpse of her daughter, Giulietta Passi Chastain. Just like everything else surrounding the baby, the photo was an unannounced surprise.

"You've got good taste, kid," she captioned the photo, which shows little Giulietta's hand clutching at a huge Piaget ruby ring. It's not only the baby's Instagram debut, but it's also one of the very first times that Chastain's even mentioned her daughter.

Chastain and her husband, Gian Luca Passi de Preposulo, have remained quiet about their baby, which Page Six reported was delivered via surrogate last year. Notoriously private, Chastain's managed to keep both her relationship with her husband and the birth of her child under the radar. Last October, rumors started swirling about a possible child when Chastain was photographed with a stroller and her husband was seen carrying a car seat into a hotel room.

Us Weekly reports that Chastain didn't confirm anything about Giulietta​​​​​​​ until yesterday's Gold Meets Golden brunch. At the event, she thanked a reporter who congratulated her on the arrival of her baby.
