Lily Allen goes braless underneath a sheer babydoll dress as she shares sizzling BTS snaps from her West End Girl tour

Lily Allen went braless underneath a sheer babydoll dress as she shared sizzling behind-the-scenes snaps from her West End Girl tour.

The singer, 41, has just completed the Manchester leg of her tour, in which she sold out both days.

Taking to Instagram on Sunday, the hitmaker sent pulses racing in the sheer pink number as she posed for a mirror selfie in her dressing room.

This was followed by racy snaps of Lily in a pink corset and black hotpants, frolicking around backstage.

She also added a gym selfie and a sweet selfie to the fun-filled photo dump.

'Arena Dump,' she captioned the post. 

Lily has taken to the stage in an array of sexy looks so far during her tour, which is a live performance of her hit album.

Showing off one of her jaw-dropping tour looks earlier this week, she posed up a storm in a racy white PVC dress as she shared behind-the-scenes snaps from her Newcastle dates. 

She has returned to the stage for a new run of performances after wrapping up her West End Girl tour earlier this year.

Lily shared a glimpse at the 60s-inspired looks that have formed her stage presence, including a flirty pink mini dress with an enormous bow detailing.

She captioned the post: 'We’re back :) uk night 1 that was funnnn newcastle.'

Lily's outing came after her ex-husband David Harbour cast a shadow of doubt over her critically acclaimed album West End Girl, which chronicled the breakdown of their relationship. 

Speaking to Variety this week, David called West End Girl, 'weird' as he discussed the reaction to the record.

The album, which has lyrics on extramarital activity and emotional manipulation, is meant to tell the story of her break-up with Harbour, with a bit of artistic license, but he doesn't see it that way.

He said: 'It was weird. I do believe that it is the privilege of every artist to use their experience to create art, and so I respect her for doing that. I can’t really say that much more, because it’s my private life.

'In spite of the fact that a lot of people don’t allow me a private life — I value it. And I also value the lives of the people that I interact with privately. I just won’t speak about that.

'Stories are complex, and that’s why I say I respect her creation of art to channel her experience. It wasn’t my experience.'

Lily previously stressed that her 14-track album, which was written in 10 days last December, consists of a 'mixture of fact and fiction', adding that fans shouldn't take the lyrics and their meaning as 'gospel'.

Most notably her hit Madeline saw Lily accuse David of having a three-year affair with a younger costume designer as she appeared to suggest the couple had an open arrangement in regards to sex, as long as it was discreet and not based on emotional connection.

Meanwhile in the song Tennis, Lily uses the racket sport as a metaphor for sex as she sings: 'So I read your text, and now I regret it.

'I can’t get my head round how you've been playing tennis/ If it was just sex I wouldn’t be jealous. You won't play with me and who the f**k is Madeline?'

The song ends with an outro repeating: 'Da, da-da, da-da, who's Madeline? (Who's Madeline?)' before it ends with: 'No, but who is Madeline, actually?'

Lily and David met on Raya and married in Vegas in 2020, but legally separated in early 2025 after four years of marriage and their divorce proceedings followed shortly after.

West End Girl explores the emotional fallout of the split. Before her marriage to Harbour, Lily was married to builder Sam Cooper from 2011 until their divorce in 2018.
