After singing about her husband’s alleged extramarital activities, Lily Allen is now bringing the receipts to her West End Girl tour.

The show, based on her 2024 album of the same name, features multiple costume changes, each one illustrating a phase in the breakdown and eventual dissolution of her marriage to *Stranger Things* actor David Harbour. By Track 8, “4chanStan,” Allen goes through her husband’s bedside drawer and discovers a Bergdorf’s receipt for a luxury handbag, purchased when she was out of town.

Fans got to see it for themselves on March 2 when Allen performed the song at Glasgow Royal Concert Hall in Scotland. Acting out the lyrics of “4chanStan,” the singer unfurled a long swath of green fabric from beside a bed propped centerstage — revealing it's printed with giant receipts.

Allen, wearing a blue lace bodysuit and burgundy hot pants, then wrapped it around herself like a dress as she sang, “You bought her a handbag / It wasn't cheap / I was in London / Probably asleep.”

But she wasn’t done. The singer then walked over to a refrigerator on the side of the stage and pulled out another long fabric, this one printed with handwritten song lyrics, which she wrapped around her head for the track’s chorus about “a sad, sad man.”

Now single, Harbour has been spotted out with other women — and one of them recently learned she’s persona non grata in Allen’s circle. Model Morgan Cozzi was asked to leave a Feb. 20 birthday party for music producer Blue May, according to TMZ. The event was held at May's Los Angeles home, where Allen recorded *West End Girl*. Although the singer wasn’t in attendance, "once guests realized Cozzi had been linked to David, the vibe shifted," the outlet reported, and security escorted her out.

Allen and Harbour separated in February 2025 after four years of marriage. Eight months later, she dropped *West End Girl*, her first album in seven years and a raw insight into the demise of their relationship. Lyrically, she refers to her ex-husband as a “sex addict” who led a "double life" and "went astray" during their marriage.

“I wrote this record in ten days in December and I feel very differently about the whole situation now,” Allen told *Interview* at the time. “We all go through breakups and it’s always f---ing brutal.”

Allen's West End Girl tour will take her through the UK, U.S., Europe, Canada, and Australia for a total of 48 shows, concluding on Nov. 1, 2026 in Perth.
