Lily Allen put on a racy display in a series of nightwear costumes as she performed her West End Girl show at Denmark's Roskilde Festival on Saturday.

The singer, 41, slipped into a pink embellished bustier for one song before changing into a metallic gold minidress. 

The critically acclaimed album explores the emotional fallout of the Smile hitmaker's split with Stranger Things actor David Harbour. 

West End Girl chronicles the breakdown of their over five-year relationship through 14 songs and has a run time of 44 minutes. 

It comes after the singer hit back at complaints from fans claiming her West End Girl tour is 'too short and expensive'.

Fans have recently vented their frustration after being charged up to £86 for a 50-minute performance with no support act. 

One user fumed on X after her performance at the weekend: 'Lily Allen at the O2. No support act. Arrived on stage at 9:10pm. All wrapped up by 10pm. Not one word to the audience.'   

Lily, 41, defiantly defended herself against the criticism with a statement on the social media platform on Monday: 'There is a support act. 

'The show has always been advertised as “Lily Allen performs West End Girl.”

'I was a few mins late as my tights were laddered and I had to change them. The show is just over an hour as it’s just the album in its entirety.

'It’s my artistic choice not to talk to the audience, the fourth wall helps with the storytelling. Most people find it to be effective. 

'I don’t want anyone to feel ripped off, everyone on this tour is really working very hard to give people the best show we possibly can, and I'm extremely proud of it.'

Tickets for the West End Girl Tour ranged from £38 to £86.

The show attracted criticism from some fans this week, who argued the ticket price was too steep for just 50 minutes of singing. 

Others bemoaned the lack of audience engagement, with the singer only returning to the stage after the final song to wordlessly accept a bouquet of flowers. 

Lily herself told Vogue the show was 'unlike anything I've done before'. 

'On previous tours, the shows have been about my personality and my interaction with the audience. This show can feel more like theater at times,' she said. 

'There's a lot of attention to detail and storytelling through props, costume, and lighting. There is an intensity that I'm really proud of and enjoying.'

It comes after David branded his ex-wife's album 'weird' as he discussed reaction to the record during an interview with Variety earlier this month. 

The hit song 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 not based on emotional connection.

The actor 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'.

Lily will kick off the North America run in September before performing in Australia, New Zealand and South America.
