Hailee Steinfeld Named Her Baby 'Beau' After Her Own Childhood Nickname — Here Is Why It's Perfect

Hailee Steinfeld hasn't officially named her baby yet, but evidence suggests the name is 'Beau' — after her childhood nickname and the name of her Substack newsletter. Here is the full story.

When Hailee Steinfeld and Josh Allen announced their daughter's birth on April 2 through Steinfeld's Substack newsletter — whose name, 'Beau Society,' derives from her childhood nickname 'Baby Beau' given when her parents alternated between 'Hailee' and 'Bailee' before settling on the former — the specific evidence chain that fans have assembled points strongly toward the baby's name being Beau or Beau-adjacent.

The specific evidence: In January, Steinfeld posted on her Substack a photograph of a knit sweater embroidered with 'Baby Beau' on the front, noting that her parents had called her 'Hailee Beau Bailee' through early childhood. She described this as 'passing down the nickname to her little one.' The newsletter that housed the birth announcement is itself named 'Beau Society' — a title that was understood as a brand name before becoming what may also be a prophetic naming choice.

For the specific non-confirmation: the birth announcement stated only 'Our baby girl has arrived!!' without a name or specific date. This is consistent with Steinfeld and Allen's specific privacy approach — they announced the pregnancy through the same newsletter, revealed the gender at birth, and are managing the name disclosure on their own timeline.

For why Beau makes perfect sense: the name — traditionally a term of endearment meaning 'beautiful' or 'handsome' in French — has been used increasingly as a given name in recent years, particularly in the Southern and Western American regions that Josh Allen's Wyoming background represents. It connects the child to Steinfeld's own childhood identity while creating a specific new meaning in the family's next generation.

For Josh Allen's specific response: the Buffalo Bills' official account posted 'Girl dad' with a thumbs-up image of Allen — two words that said everything necessary. Allen's recovery from his broken foot and his preparation for the next NFL season now has a specific new dimension of motivation.

This is, purely as a human story, exactly the kind of spring news that April 2026 needed alongside everything else it has produced.
