Lily Allen wears 'revenge dress' hinting at ex-husband David Harbour cheating in performance

Lily Allen fans are flocking online in awe of the singer's 'receipt dress' that she debuted on her ongoing tour, which seemingly takes aims at ex-husband David Harbour.

Allen has been taking to the stage on her world tour to perform her 2025 album, West End Girl.

The album sent Allen's fans squealing, not only for being the singer's latest music to be released in a whopping seven years since 2018's No Shame, but also over what her songs were about.

The deeply personal album followed the British singer's break-up with ex-husband David Harbour in early 2025.

And it certainly didn't half-ass it when it came to seemingly sharing an insight into Allen's perspective on her marriage to the Stranger Things star, and why she believes it broke down - with the album alleging that she was cheated on.

Apparently singing about it in her album wasn't enough either, nor performing it on stage every night, as the show also sees Allen don a piece of fabric labelled by social media users as a 'revenge dress' which is made up of receipts.

Allen's show is set up as if it's a play and sees her run through the entirety of her latest album.

Incorporating multiple costume changes, the eighth track '4chanStan' sees Allen go through a bedside drawer on stage, according to a clip of the show shared online by Live Gig Videos.

The singer discovers a receipt in the draw for a luxury handbag, with the date of the Bergdorf Goodman receipt being when she was out of town.

Allen sings: "You bought her a handbag / It wasn't cheap / I was in London / Probably asleep."

The moment is further emphasised in Allen's outfit too, the singer taking a long swath of fabric from the bedside which appears to be printed with giant receipts, wrapping it around her to form a dress.

And it's not taken long for social media users to weigh in.

One Twitter user noted they don't think the receipts are actually 'real'.

I mean, Allen is on stage, performing a show and her album is called West End Girl, so dramatic license and all that. Real receipts or not, you get the gist.

Another said: "A petti coat."

And responding to some who simply questioned why Allen hasn't moved on, a third wrote: "Everyone saying 'move on' but it’s literally the theme of the album she’s touring rn…"

In discussion with Interview, Allen previously said: "I wrote this record in ten days in December and I feel very differently about the whole situation now. We all go through breakups and it’s always f**king brutal."

UNILAD has contacted representatives of David Harbour for comment.
