Hailee Steinfeld has given birth to a baby girl.

The Pitch Perfect actress and her husband Josh Allen have confirmed they have welcomed their first child into the world, but haven't offered any details about the tot, including her name or when she was born.

The couple announced in a post shared to Hailee's Beau Society Substack on Thursday (02.04.26): "Our baby girl has arrived!!

"We're feeling incredibly grateful and blessed and savouring these early moments. Thank you so much for the love and well wishes."

Last month, the 29-year-old actress celebrated her impending new arrival with 30 of her closest female friends and family members at a backyard baby shower.

Hailee - who married Josh last year - wrote on her Substack: "On a sunny Saturday in LA, my mom and about 30 women I love so much gathered in my most comfortable place -- my backyard -- for a baby shower. My mom planned the entire gorgeous thing."

Hailee explained that there was "no baby shower theme, per se, but a subtle nursery rhyme thread was woven throughout the decor".

The Sinners star also noted that nursery books were scattered "everywhere".

Hailee said: "Everyone brought a book, so this baby is building quite the little library."

What's more, Hailee's mom even installed a knitting station for her guests, so they could create something special for her baby.

She added: "It's a very full-circle moment for me because my mom took up knitting when I made my first movie. She was sitting in a trailer all day and needed something to do. It was Sudoku or knitting, and she chose the latter. Our family would joke that she was going to knit the red carpet because she didn't stop.

"She taught me how to knit way back when. I can't really cast on or off, but I was able to knit a square to put on this baby's blanket. I feel like I reopened a fun hobby."

Hailee and Josh tied the knot in May 2025 and the actress previously admitted that she feels very lucky to have him in her life.

In a previous newsletter, Hailee gushed: "I literally thank God every day that I found my person, and it's the greatest thing in the world. Life makes sense. Everything makes sense. I feel like I am stepping into the version that I've always dreamed of being, having so much to do with being with him."
