Hailee Steinfeld solves the mystery and posts a strange photo of Josh Allen with his daughter Harper

Hailee Steinfeld and Josh Allen have offered fans a rare look at their seven-month-old daughter, Harper Haize Allen , with a Halloween celebration that turned their family into the centre of an elaborate storybook fantasy.

The couple hosted an Alice in Wonderland-themed party, appropriately named "Allen's in Wonderland", with Steinfeld sharing details through her Beau Society platform.

However, one particular image has attracted attention: a glimpse of Allen with his daughter, whose face remains carefully out of view.

The photograph has added another piece to the mystery surrounding Harper's appearance. Since welcoming their first child in April, Steinfeld and Allen have largely kept her away from the public spotlight, sharing occasional details without regularly showing her face.

This time, the couple revealed more about the little girl's Halloween outfit. Harper was dressed as Alice, wearing a pale blue satin dress with a sparkling tulle underskirt, white tights and black Mary Jane shoes.

The images showed only part of her appearance, maintaining the parents' preference for keeping their daughter out of full public view.

The party's decorations were equally elaborate. A giant clock-shaped entrance led guests through a black-and-white tunnel before they reached a setting filled with oversized playing cards, chess pieces, red flowers and a large mushroom.

A sign pointing towards Wonderland helped establish the theme, while marquee lettering displayed the words "We're all mad here…"

The event was shared on Beau Society's Instagram account, with the post also acknowledging the team responsible for organising the celebration, including the venue, florists, photographer and design specialists.

Allen and Steinfeld take centre stage as the King and Queen of Hearts

The hosts made sure their own costumes matched the occasion. Steinfeld , known for her role in Sinners, wore a black velvet gown featuring roses around the neckline, long gloves and a heart-shaped pendant. A playing-card cape completed her Queen of Hearts-inspired appearance.

Allen , meanwhile, dressed as the King of Hearts, wearing a black jacket decorated with playing-card designs, black trousers and a cape with red lining. Both wore matching crowns, making the couple the central characters in their customised Wonderland.

The celebration also brought together several members of the Buffalo Bills family. Raven Moore , the wife of Allen's teammate DJ Moore , shared additional photographs showing the impressive entrance and other details from the event.

DJ and Raven embraced the Charlie and the Chocolate Factory theme, dressing as Augustus Gloop and Violet Beauregarde.

The Halloween festivities came after a significant year for the couple. Allen and Steinfeld married in 2025 before announcing the arrival of their daughter on April 2, 2026.

Steinfeld initially kept the baby's name private, eventually revealing it in a heartfelt letter published through Beau Society in June. She confirmed that their daughter is called Harper Haize Allen .

The actress has also spoken about how motherhood has changed her outlook, while Allen has described fatherhood as one of the most rewarding parts of his life.

The quarterback previously discussed how the couple had adapted their evening routine around their daughter, even finding time for crossword puzzles and word games once Harper had fallen asleep.

For fans hoping to see more of the newest member of the Allen family, the Halloween photographs offered another small glimpse.

But the decision not to reveal Harper's face suggests that, despite their public profiles, Steinfeld and Allen remain determined to give their daughter some privacy as she grows up.
