Lily Allen puts on a racy display in a pink silk bra as she shares behind-the-scenes snaps from West End Girl tour

Lily Allen put on a very racy display in a pink silk bra as she shared behind-the-scenes Instagram snaps from her West End Girl tour on Saturday.

The 40-year-old singer shared multiple shots of herself wearing lingerie as she prepared for her concert in Sheffield. 

Lily also shared photos of multiple outfit options for the tour, including a strapless leather bodycon dress and a pale pink jacket with a dramatic ruffled neckline. 

The West End Girl album is famously an ode to her ex-husband David Harbour, 50, and their acrimonious breakup.

During her performance of the track 4Chan Stan, during which Lily sings about discovering a partner's infidelity, Lily wrapped herself in a long swath of fabric printed with lyrics and receipts. 

Fans in the audience for the first two shows at Glasgow and Liverpool this week have spotted that the receipts are from tequila bars and Bergdorf Goodman, detailing items her ex bought for other women.

The Bergdorf reference is a direct nod to the song, in which she sings 'Never been Bergdorf's, but you took someone shopping there on May 24. You bought her a handbag. It wasn't cheap. I was in London. Probably asleep.'

Lily unravelled the receipt dress during the song, revealing a custom Self-Portrait ruffled sheer lace bodysuit and burgundy patent hot pants underneath. 

The dress isn't the only on-stage reference to the album's cheating lyrics as during the track Pussy Palace Lily sings from a bed with a Duane Reade bag beside her — mirroring the track’s lyrics about discovering a bag full of sex toys at her husband's second apartment. 

The new album was nominated in three categories at the 2026 BRITs but unfortunately she didn't walk away with any wins during last week's ceremony.

During the West End Girl tour show, Lily changes into six looks over the 45-minute set, with pieces including a sheer Valentino negligee, a tweed Valentino skirt suit and a black leather bullet-bra bustier dress by 16Arlington, the design house Lily walked the runway for last year. 

The show’s incredible looks were styled by Interview magazine editor-in-chief Mel Ottenberg, who revealed on Instagram this week that his long-time friend Lily 'got me out of tour styling retirement 20 years after I first styled her.'

After Lily's first show, some fans admitted they were left confused by the format and the fact she was only on stage for 45 minutes.

While they delighted in the time Lily was on stage playing her new album from beginning to end, some took issue with the first half of the show.

A string trio entertained the audience with a 55-minute instrumental performance of some of her biggest hits, including Not Fair, The Fear and Smile.

This segment of the gig received mixed reviews, as some branded it 'funny and camp' – while others said it was akin to a 'primary school assembly sing along'.
