Allen sings on the record about how this led to an “arrangement” with Harbour where he could be with other women, but the rules were “there had to be payment, it had to be with strangers”.
But, before long, Allen hears of a relationship her husband appears to have with “Madeline” – a pseudonym – which falls outside their arrangement.
Harbour has not publicly commented on the content of the album.
However, he appears to still have a relationship with Allen and her children, and was seen, external taking her daughters to a theme park last weekend.
All 14 songs on West End Girl were written by Allen, mainly in collaboration with her musical director Blue May.
Allen has suggested that some of the songs are written “in character”, saying that the lyrics “could be considered autofiction” – a genre that combines autobiography and fiction.
She rose to fame in 2006 with her debut album Alright, Still, and had number one hits including Smile, The Fear, and her cover of Keane’s Somewhere Only We Know, which was featured in a John Lewis advert.
She had two number one albums in the UK, It’s Not Me It’s You and Sheezus, while her 2018 record No Shame was nominated for the Mercury Prize.
She released a candid memoir, My Thoughts Exactly, in the same year, but took a break from music shortly afterwards, and began dating Harbour in 2019.
The singer will perform West End Girl in the order the songs appear on the record for her tour in March.
Tickets for the tour, which launches in March 2026, go on sale on 7 November.
