Lily Allen Channels Madeline for Halloween, Playfully Addressing Marriage Rumors

Lily Allen took Halloween celebrations to the next level this year, dressing as Madeline, the renowned character from the beloved children’s book series. This costume choice aligns with her recent single titled “Madeline,” featured on her latest album, *West End Girl*. The song narrates a raw confrontation between a woman and a character named Madeline, who is implicated in an affair, adding depth to Allen’s Halloween aesthetic.

Lily Allen’s Halloween Costume and Album Release

On November 1, 2025, Allen showcased her playful Madeline costume on TikTok, dancing to Cardi B’s “Magnet.” The outfit was a striking representation of the character, complete with the signature blue coat, red bow, black Mary Janes, and white ankle socks. Her look was finalized with an orange wig and a straw hat, capturing the essence of Madeline perfectly.

Halloween Event and Celebrity Attendees

Allen wore her costume to an exclusive Halloween party thrown by Vas J Morgan and Michael Braun at Chateau Marmont in Los Angeles on October 31. The event attracted a star-studded guest list, including:

• Paris Hilton
• Orlando Bloom
• Kaia Gerber
• Tiffany Haddish

Exploring Themes of Trust and Relationship Dynamics

In her new song “Madeline,” Allen delves deep into themes of trust and betrayal within relationships. The narrative explores her feelings towards the woman she believes is involved with her husband. The lyrics raise provocative questions about the nature of their relationship, asking whether it is purely physical or if emotional connections exist.

Following her separation from actor David Harbour in February, Allen shared insights into her latest project, referring to it as “autofiction.” In an interview with *Perfect Magazine*, she explained that while her experiences influence her music, the stories are not strictly autobiographical.

Insight into Allen’s Relationship and Music

Allen married Harbour in Las Vegas in September 2020, with their relationship first emerging in 2019. Her album *West End Girl* encompasses tracks that reflect complex relationship dynamics, including “West End Girl,” where a partner doubts her abilities, and “Pussy Palace,” which hints at infidelity involving the couple’s secondary residence. The track “Dallas Major” further explores her feelings about being in an open marriage, emphasizing her struggles.

Representatives for both Allen and Harbour have yet to provide comments as of November 2, following the public interest sparked by her recent social media posts.
