Lily Allen made a pointed reference to her estranged husband David Harbour’s alleged infidelity by dressing as “Madeline” for Halloween 2025, a character she named in a song about the affair. The costume, shared on social media, continues the public fallout from their recent divorce.
On Halloween night, Lily Allen stepped out in Los Angeles wearing a costume inspired by Madeline, the intrepid French heroine from the classic children’s book series. She documented the look in a TikTok video, where she pranced down a hallway dressed in a blue collared pea coat, red neckerchief, straw hat, Mary Jane shoes, and a bright orange wig. The video was set to Cardi B’s “Magnet,” and Allen captioned it with a cryptic question: “Who IS Madeline though, actually?” This immediately sparked speculation among fans and media outlets about the underlying message, with many interpreting it as a deliberate dig at Harbour.
The costume is a direct nod to Allen’s new album, “West End Girl,” released earlier this year, which includes a track titled “Madeline.” In the song, Allen details a phone call with the woman Harbour allegedly cheated with, exploring whether their relationship had emotional depth or was purely physical. She sings about the rules of their open marriage, which required Harbour to pay for any sexual encounters and keep them discreet, but “Madeline” crossed a line by becoming more than a stranger. This artistic expression has turned personal turmoil into a public narrative, blending revenge with creative release.
Allen and Harbour, who married in 2021, announced their separation in February 2025 after four years of marriage. The divorce filing was submitted last month, and Allen has been open about the emotional toll, including a stint in a treatment center for turmoil related to the split. The album “West End Girl” serves as a cathartic outlet, with “Madeline” being one of several tracks that address the breakdown of their relationship and Harbour’s infidelity, highlighting how celebrity breakups often play out in the media spotlight.
The woman referred to as “Madeline” in the song was later identified as Natalie Tippett, a costume designer who worked with Harbour on a 2021 Netflix film. It is alleged that their affair began during the production, violating the terms of Allen and Harbour’s open relationship. This revelation added a layer of personal and professional betrayal to the ongoing public drama, as it connected the infidelity to their shared industry, making the situation more intricate and emotionally charged for those involved.
In response to the album’s release and the subsequent media attention, Harbour has largely remained silent, though he was spotted taking Allen’s two daughters, Ethel Mary and Marnie Rose, to Universal Epic Universe in Orlando for a day out. This move was interpreted by some as an attempt to maintain normalcy for the children amid the parental conflict. Page Six reported that they reached out to Harbour’s representative for comment but did not receive an immediate response, indicating a strategy of avoidance in the face of public scrutiny.
Allen’s Halloween costume is the latest in a series of public jabs at Harbour, following events like her album launch party where she distributed butt plugs that doubled as USBs containing the album. These actions highlight her use of art and public appearances to process and publicize her side of the story, blending personal vendetta with promotional strategy. It underscores a trend where celebrities leverage social media and creative works to control narratives during personal crises, engaging fans while settling scores.
The ongoing saga between Allen and Harbour illustrates the complexities of modern celebrity divorces, where social media and music become platforms for airing grievances. As both parties navigate their separation, the public spectacle continues to draw attention, with fans and critics alike weighing in on the drama. What comes next remains uncertain, but Allen’s creative expressions suggest she is far from done addressing the past, potentially setting the stage for further revelations or reconciliations in this highly visible split.
