Hailee Steinfeld gave a first look at her daughter while celebrating Mother’s Day.

The “Sinners” star took to Instagram Monday to post an adorable photo of the newborn, whose name hasn’t been revealed, gripping her hand.

Steinfeld shied away from showing her little one’s face, but shared a separate snap of the latter wearing a polka-dot onesie.

Additionally, the actress, 29, shared a picture of a homemade breakfast spread and a decorated cake that read, “Happy Mother’s Day.”

“A day late but simply obsessed with this 💗,” she captioned the photo.

Steinfeld received a lot of love and support in the comments, including from her “Hawkeye” co-star Jeremy Renner, who wrote, “Happy New Mothers Day !!! 🙏🏼🙏🏼🙏🏼❤️❤️❤️❤️. I am so very happy for you.”

Allen, 29, also paid tribute to his wife by resharing her photos via his Stories and writing, “My whole world.”

Steinfeld and the Buffalo Bills quarterback announced the arrival of their daughter on April 2.

“Special delivery,” they titled a Substack post.

“Our baby girl has arrived!!” they wrote. “We’re feeling incredibly grateful and blessed and savouring these early moments.”

At the time, the duo hinted at their bundle of joy’s name, showing off a onesie that read, “Baby Beau.”

The “Pitch Perfect” star and Allen revealed they were expecting their first child together in December, alongside a video of themselves in the snow.

At the time, Steinfeld was seen lifting a sweater that read “Mother” to reveal her bump.

Steinfeld and the NFL star started dating in 2023 and got engaged the following year.

They tied the knot in front of friends and family in Montecito, California, in May 2025.
