Lily Allen stripped down to her underwear as she headlined Boardmasters Festival with her West End Girl show in Newquay on Saturday.

The singer, 41, had a huge musical comeback last year with her album West End Girl, which detailed her tumultuous split from husband David Harbour, and allegations he cheated on her.

And Lily pulled out all the stops as she took to the stage to perform the break-up album in full.

Dressed in a gold ruched dress, Lily later stripped it off to reveal a nude satin corset bodysuit and black lace underwear.

She later donned a sheer pink gown as she lay on a bed.

West End Girl is a 55-minute performance which is structured more like a one-woman stage play rather than a traditional concert. It features no crowd interaction or encores.

Boardmasters Festival is the UK's biggest combined surf and music festival and welcomes over 50,000 attendees across two coastal sites.

It features around 90 artists playing across multiple stages with Saturday also featuring Nia Archives, Ren, Alessi Rose and Example.

It comes as Lily is set to star in a new Prime Video documentary charting her 'extraordinary' rise to fame.

The singer has had a triumphant return to the music scene with her comeback album West End Girl, and will now appear in the feature-length film looking back at her life.

The retrospective documentary will chart Lily's journey, from the "Queen of MySpace" who changed the rules of the music industry, to the cultural force she is today.

As a pioneering woman in modern music, Lily's sharp wit and candid storytelling directly paved the way for a generation of today's biggest female artists.

Featuring interviews with those who know her best, the documentary builds a rich and revealing portrait of an artist defined by her creative fearlessness.

The documentary will be directed by award-winning film-maker Mat Whitecross, who previously directed Oasis: Supersonic and Coldplay: A Head Full of Dreams, and will be released on Prime Video in 2027.

Earlier this year, the Smile hitmaker opened up about the toll her tumultuous last year has taken on her daughters as she admitted they are struggling to readjust following the family's relocation to the UK.

The star revealed that Ethel and Marnie are finding it difficult to navigate changes after moving from New York back to the UK.

Lily, who released her West End Girl album that detailed ex David Harbour's alleged affair whilst they were together, returned home after the breakdown of her marriage to the 51-year-old.

Speaking candidly on her podcast Miss Me? Lily said: 'I've done quite a lot this year.

'I've finished an album, I got a boob job, I had a nervous breakdown, I went into hospital for a bit, I came out, I did some podcasting for a while, then I played one of the hardest tracks in theatre and killed myself [in the role of Hedda Gabler] every night for seven weeks.'

She continued: 'My kids are f***ing mental at the moment... They are really developing their personalities. It's just a lot. There's a lot of questions.

'There's a lot of change in our lives at the moment. We've changed houses, we've changed countries, we've changed schools, and it's a lot.'
