Morgan Cozzi — a woman who was linked to Lily Allen’s estranged husband, David Harbour, last year — was reportedly asked to leave a party for the singer’s producer.
On Feb. 20, Cozzi showed up to a birthday bash for producer Blue May at his Los Angeles home, sources told TMZ.

The outlet reported that although Allen wasn’t at the party, many of her close friends and collaborators were at the residence — the same place where the singer recorded her latest album, “West End Girl.”
Cozzi, who was reportedly invited as a “friend of a friend,” was asked to leave the festivities after people realized she was the woman who allegedly had relations with Harbour.
Page Six has reached out to Cozzi, Allen and Harbour for comment but did not immediately hear back.

Last November, photos surfaced of the “Stranger Things” actor and the model enjoying a romantic stroll in New York City.
The pair appeared to be in good spirits, as they smiled and laughed throughout their conversation.
One month prior, Allen, 40, released her scathing album, “West End Girl,” in which she sang about the alleged infidelity in her open marriage to Harbour.

In the song “P–sy Palace,” Allen accused her partner of having a “double life” and sang about the time she discovered a stash of adult toys, lube and “hundreds” of condoms.
On the track “Madeline,” the British songstress sang about reaching out to her husband’s mistress after seeing their alleged texts.
“We had an arrangement / Be discreet and don’t be blatant / There had to be payment / It had to be with strangers / But you’re not a stranger, Madeline,” she sang.
One of the women who allegedly had an affair with Harbour was revealed to be Natalie Tippett. The costume designer and the “Hellboy” star met while filming a movie in New Orleans in 2021.

In February 2025, news broke that Allen, who married Harbour in 2020, and the actor were divorcing after four years of marriage.
The “Hard Out Here” singer then revealed that she had gone to a treatment center for “emotional turmoil.”
Allen filed for divorce last September.
