Lily Allen Thanks Fans For 'Validating' $10,000 Weekly Rehab Treatment With Revenge Album

Lily Allen's new album “West End Girl” may have just marked the beginning of her healing.

Released in the wake of her split from David Harbour, the 14-track body of work lays bare the ordeal she experienced during the breakup and has already been widely termed a "revenge album."

Between dropping the music work, which fans welcomed heartily, and seeking professional support, Allen is taking steps toward rebuilding herself, and she recently expressed gratitude. 

In a recent interview, the 40-year-old singer said she felt genuinely seen by the public's reaction to the project.

"Firstly, I'm overwhelmed and massively grateful," Allen told Anthony Mason on CBS Mornings, adding that the project's viral success has helped her process her emotions.

Given that she has always written music as a form of healing, Allen said it feels "affirming and validating" when listeners connect with the pain behind her lyrics and acknowledge how "messed up" her experience was.

The British star also revealed she checked herself into an £8,000 ($10,000) per week treatment center after the separation. Reflecting on that difficult period, she joked, "Now I know why I had to check myself into a treatment center!"

About ten months before the release, Allen was reportedly seeking professional help as the breakup impacted her mental health. 

According to Daily Mail, her emotional state worsened after returning from a holiday to their New York home in January, especially due to fears that Harbour might have been elsewhere in the city with another woman.

A source said the situation was painful for Allen, noting that the “Stranger Things” actor who once felt like her "savior" had become a trigger.

After settling her daughters, Ethel and Marnie, back into their school routine, Allen immediately flew to rehab. She even arrived a day earlier than planned because she felt unstable and desperate for help.

Discussing the inspiration behind the work, Allen described it as "an act of desperation" created during the collapse of her four-year marriage.

Though the storyline centers on a deceptive partner, Allen has clarified that the album is both true and fictional. While she initially considered keeping it private, she soon realized that hiding it would prevent her recovery. 

Now that it's out, she says the release has been "utterly liberating." In her words:

"It was kind of hellish having it in the background. I don't know. I just feel like I couldn't; it said everything that I needed to say. And I felt like I couldn't really like get on with my life until I'd said it."

Since the drop, one of the biggest fan questions has been about "Madeline," the mysterious name Allen mentions in the track "Tennis." Many wondered whether the girl was connected to Harbour.

The “Smile” singer later clarified that it isn't a real person but a fictional character, before hinting more at what may have occurred in her union, as The Blast reported.

“Intimacy is inherently messy,” Allen said. “There are usually agreed-upon boundaries in relationships, but whether those boundaries are adhered to or not is becoming a grey area all of a sudden.”

The speculation began after fans dissected her lyrics, especially the part where she confronts a troubling text message and questions who is “Madeline?” To many listeners, this dynamic felt like Allen's own version of Dolly Parton's “Jolene,” a confrontation with a symbolic romantic rival.

Since ending her relationship with Harbour, which was filled with cheating allegations, Allen has been insistent on her stance about not liking open relationships, emphasizing it’s not something she would pursue. 

While acknowledging that younger generations seem more comfortable with the idea, the “Not Fair” singer said her own upbringing in an unstable home has shaped her perspective.

Now grown up, she wants to be the center of attention in her romantic life, and she does not want to share that space.

When it comes to her dating life, the Grammy nominee has neither confirmed nor denied seeing anyone. However, she knows what she wants in a partner going forward.

In an October interview, which The Blast covered, Allen explained that she isn't interested in dating another celebrity. According to her, in England, going on a date with her feels "like a novelty," an experience she says ultimately creates a barrier rather than a genuine connection.

She then shared her experiences with dating apps, saying that the people she met were nothing like the person she was missing.
