Hailee Steinfeld reveals pregnancy with baby bump photos and name "Beau" on Substack.

Hailee Steinfeld, 29, has shared new photos of her baby bump in a January 2026 post on her Beau Society Substack, revealing a yellow onesie labeled “Baby Beau.” The name “Beau” holds personal significance, stemming from a childhood nickname tied to her parents’ original naming dilemma between Hailee and Bailee. Steinfeld, who married NFL quarterback Josh Allen in May 2025, first announced her pregnancy in December 2025. The couple has shared glimpses of their journey, including moments with Allen, but has not disclosed the baby’s gender or due date.
