Hailee Steinfeld gave fans a little look into her family life this week, and it was her daughter Harper who ended up stealing the spotlight. The actress and her husband, Buffalo Bills quarterback Josh Allen, recently celebrated their first Halloween as parents, sharing a few sweet details from a family celebration inspired by Alice in Wonderland.
The couple hosted a belated Halloween party on November 2, calling it “Allen’s in Wonderland.” Steinfeld later shared photos and behind-the-scenes moments through her Beau Society newsletter and its Instagram account. While the event featured plenty of elaborate costumes, fans were especially interested in seeing Harper dressed up for her first Halloween.
For the occasion, Steinfeld stepped into the role of the Queen of Hearts, while Allen dressed as the King of Hearts. Their daughter, Harper Haize Allen, appeared in a baby-blue outfit inspired by Alice, complete with white tights and little black shoes. It was a small glimpse, but enough to get fans talking about the family’s celebration.
Hailee Steinfeld and Josh Allen Turn Halloween Into a Family Celebration
The Halloween party was more than just a costume night for the couple. Steinfeld revealed that hosting the event again felt particularly special, especially after taking a break from the tradition. She also joked about the timing, explaining that everyone managed to have a great night despite celebrating a couple of days after Halloween.
Several Buffalo Bills players and their partners joined the festivities, making it a bigger gathering than a typical family Halloween celebration. The decorations followed the Wonderland theme, with guests getting creative with their costumes.
Harper also had a few different looks throughout the holiday. In an earlier newsletter update, Steinfeld shared that her daughter had dressed up as a bat, a Cabbage Patch doll and a Highland cow. The last costume was apparently Josh’s pick, giving the quarterback a little say in the family’s Halloween wardrobe.
Motherhood Has Changed the Way Hailee Steinfeld Sees Herself
The Halloween photos weren’t the only reason Steinfeld caught people’s attention this week. In her November 6 Beau Society newsletter, she answered a reader’s question about what watching Harper grow up has taught her about herself. Her response offered a more personal look at how she has been adjusting to motherhood.
Steinfeld explained that she expected becoming a mother to change the way she loved another person, but she hadn’t anticipated how much the experience would help her discover new things about herself. She said Harper has made her more patient and present, while also helping her appreciate the little moments that might otherwise go unnoticed.
That reflection feels especially meaningful coming from someone whose career has kept her in the public eye from a young age. Between acting projects, music and public appearances, Steinfeld has spent much of her life working in a fast-moving industry. Motherhood, however, seems to have given her a different way to look at time and everyday experiences.
She also spoke about learning to give herself the same understanding she often encourages others to have. It’s advice she admits she doesn’t always follow herself, but one she is continuing to work on.
Hailee Is Enjoying the Little Moments With Harper
During her November 5 appearance on Live with Kelly and Mark, Steinfeld also shared a little more about life with her daughter. She joked about how quickly Harper seems to be growing, saying that sometimes it feels as though her baby is six months old, four weeks old and five years old all at once.
She also revealed that Harper has started crawling and is already keeping her busy. Like many first-time parents, Steinfeld couldn’t help feeling that her daughter was particularly clever as she reached new milestones.
The actress has gradually shared these everyday moments through Beau Society, rather than regularly putting her family life on display across social media. From morning routines with Harper to small updates about her development, her newsletter has become a more personal way for fans to hear from her.
Steinfeld and Allen married in May 2025 and welcomed Harper in April 2026. Although they generally keep their relationship away from the spotlight, these recent updates show a happier, more family-focused side of their lives. And judging by Steinfeld’s latest reflections, she’s enjoying this new chapter just as much as the big moments that come with it.
