Lily Allen has found an unexpected ally amid the storm, her estranged husband David Harbour's other ex.

Alison Sudol appears to be taking Allen's side after the singer's new album spilled details of an alleged affair. This twist comes as Harbour continues to spend quality time with Allen's children, showing up at a theme park with his step kids despite the ongoing separation.

Lily Allen and David Harbour famously began dating in 2019 after his split from Alison Sudol, and the pair tied the knot the following year in a spontaneous Las Vegas ceremony.

When Allen unveiled her upcoming album "West End Girl" on Instagram, Sudol, who dated Harbour back in 2018, showed up in the comments with a string of flame emojis. Fans instantly took notice, reading her comment as more than just casual support.

The timing is hard to ignore. Allen recently filed for divorce from the actor and is now releasing music packed with what sound like sharp jabs at an unfaithful partner. Tracks like "P-ssy Palace" and "Dallas Major" hint at infidelity, addiction, and a marriage that unraveled behind the scenes.

According to Page Six, Sudol has not said a word about the songs themselves, but her reaction to Allen's post seems to say plenty. In addition, the record's lyrics strongly suggest that Harbour may have strayed during his marriage, though Allen never names him outright.

Allen's latest album is turning heads and not just for its sharp look at her split from Harbour. One track in particular has fans buzzing over a woman named "Madeline," a name Allen drops while singing about betrayal and broken trust.

In the song, the 40-year-old calls out an unfaithful partner, questioning his honesty and hinting at a third person involved. "Who the f-ck is Madeline?" Allen asks in the chorus, later admitting she read a text she wished she had not.

The raw emotion in the lyrics immediately sent listeners into detective mode, speculating about the identity behind the name. After the uproar, Allen clarified that "Madeline" is not real, but a character created to tell a story, not a hidden reference to anyone specific.

They purchased the 19th-century property in 2021 for around $3.3 million and later transformed it with the help of designer Billy Cotton and architect Ben Bischoff of MADE.

The Blast noted that Allen described online dating as "depressing," admitting she often caught herself searching for traces of her ex in the people she met. Despite that, she is learning to focus on herself and what she truly wants.

One thing she is sure of? She is steering clear of celebrities. "I'm not really looking to go out with another famous person," the TV personality stated plainly.
