Trick or treat.
Lily Allen took another swipe at her estranged husband, David Harbour, by dressing up as the lover she named in her song ‘Madeline’ for Halloween 2025.
On Friday, the “Smile” singer took to TikTok to share a video of herself dressed as Madeline from the popular children’s book series.
In the clip set to Cardi B’s “Magnet,” Allen, wearing a blue collared peacoat, red neckerchief, straw hat, Mary Jane shoes and bright orange wig, bounces down a hallway while looking straight into the camera.
At one point, the 40-year-old British singer smoked a neon green e-cig before turning around and dancing back down the hallway.
“Who the hell is Madeline, by the way?” she captioned the post.
Fans took to Allen’s TikTok comments section to share their thoughts on the singer’s recent shady moves.
“No notes at all,” one user wrote.
“Crashing out is very justified,” another added.
“You had the opportunity to do the funniest thing and you did it 😂,” a third person commented.
“I thought, ‘🤔 Let’s see how Lily’s Halloween turns out.'” Loved watching 👏👏👏,” a fourth netizen said.
Page Six reached out to a Harbor representative for comment, but did not immediately receive a response.
In February, news broke that Allen and the “Stranger Things” actor, 50, were divorcing after four years of marriage. The “Hard Out Here” singer later revealed that she went to a treatment center due to “emotional turmoil.”
Allen filed for divorce last month.
The pop star revealed details about Harbor’s alleged infidelity on her newly released album West End Girl.
In the song “Madeline,” Allen sang about Harbor breaking the rules of an “open” marriage.
The woman was later identified as costume designer Natalie Tippett, with whom Harbor allegedly began an affair while co-starring in the 2021 Netflix film.
The day after the album was released, Harbor dismissed the drama by taking Allen’s daughters Ethel Mary, 13, and Marnie Rose, 12, to Universal’s Epic Universe in Orlando, Florida, for a day of fun.
