Hailee Steinfeld and Josh Allen have welcomed their first child.

The couple announced the birth of their daughter Thursday via Steinfeld’s Substack newsletter Beau Society.

“Our baby girl has arrived!!” they wrote in the post. “We’re feeling incredibly grateful and blessed and savouring these early moments. Thank you so much for the love and well wishes.”

The note is signed “Love, Hailee and Josh.”

The birth comes after the Sinners actor, 29, made a pregnant red carpet appearance at the 2026 Golden Globes in January, which she attended alone as her Buffalo Bills star husband took on the Jacksonville Jaguars.

Steinfeld and Allen, both 29, mostly kept the pregnancy private, with the baby’s gender just being revealed upon her birth. However, the “Starving” singer sometimes shared details from the expecting parents on Beau Society, where she regularly posts life updates and musings.

“This week, I was sitting on the couch in my family room, and the reality that our little family is about to grow really started to settle in,” Steinfeld wrote in the message shared February 20. “Of course, I have all the to-do lists (which you know I love), and I’ve been busy with research and the general life reorganization that happens when you’re about to have a baby.”
