Hailee Steinfeld and Josh Allen welcome their first baby

A mini Buffalo Bills fan has arrived!

Hailee Steinfeld gave birth to her and husband Josh Allen’s first child.

The singer announced the happy news in a Substack post Thursday titled “Special delivery…”

“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,” she said before signing off as “Love, Hailee and Josh.”

The couple announced in a snowy December 2025 Instagram video that they were expecting a baby.

The actress, who captioned the sweet footage with a heart emoji, lifted up her “Mother” sweater to reveal her bump in the social media upload.

The NFL quarterback, 29, kissed his wife’s bare belly in the clip.

The reveal came one month after Steinfeld, also 29, sparked pregnancy rumors by hiding her stomach with a structured Stéphane Rolland dress at the 2025 Governor Awards.

She put her bump on display the next time she walked a red carpet at January’s Golden Globes 2026.

At the time, the Oscar nominee posed in a beaded pink Prada gown — and gushed via Instagram about her “night out with [her] newest plus one.”

The “Sinners” star hinted at the name she and Allen had chosen for their little one that same month in her Beau Society newsletter.

The “Starving” singer included a photo of a onesie reading, “Baby Beau.”

Steinfeld and Allen have been together since 2023, with the athlete getting down on one knee in November of the following year.

The pair walked down the aisle in Montecito, Calif., in May 2025.

That November, Steinfeld told Bustle that she was “of course” thinking about having children with her husband.

She raved over Allen elsewhere in the interview, saying, “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.”

Prior to their romance, Steinfeld was linked to influencer Cameron Smoller and former One Direction member Niall Horan.

Allen, for his part, previously dated college sweetheart Brittany Williams.
