Actress Hailee Steinfeld and Buffalo Bills quarterback Josh Allen have officially announced the name of their newborn daughter. In a deeply personal letter published to her Beau Society Substack newsletter on June 19, Steinfeld revealed the couple named their first child Harper Haize Allen.
Allen quickly reshared the newsletter announcement to his Instagram account, adding a red heart and a teary-eyed emoji to the post. The couple, who married in May 2025, quietly welcomed the baby two months ago in April.
The middle name carries immediate significance for Steinfeld’s longtime fans. The moniker Haize is a direct callback to her breakthrough 2015 debut EP, HAIZ, acting as an 11-year homage to the launch of her pop music career.
The newsletter update took the form of a letter addressed directly to the infant. Steinfeld wrote, “Dearest Harper. I’m in awe of you. You’ve been here for only a short while now, and somehow it feels as though you’ve always been ours.”
Steinfeld emphasized during a recent livestream that her priority for her first summer as a mother is to remain completely present, indicating a slight step back from her professional obligations. Allen is currently back on the field attending the Bills’ minicamp. The quarterback is actively recovering from a foot injury sustained last season, though he recently noted that fatherhood has brought out the best version of himself in all aspects.
