Lily Allen didn’t hold back when taking a swipe at her estranged husband, David Harbour, during a recent event celebrating her latest musical release.

According to The London Standard, the singer handed out rather unconventional party favors—specifically, butt plugs—at the launch party for her new album, “West End Girl.”

Attendees of last Friday’s gathering reportedly left with these blue and white polka-dotted sex toys, which directly tie into the biting lyrics of her track “P—y Palace.” The song is said to address Harbour’s alleged infidelity.

Speculation arose on social media, with some guests suggesting that these sex toys were actually cleverly disguised USB drives containing her album. However, representatives for Allen have not yet confirmed whether the items were authentic or purely promotional.

In “P—y Palace,” Allen, 40, sings candidly about her relationship woes: “Sex toys, butt plugs, lube inside / Hundreds of Trojans, you’re so f—ing broken / How’d I get caught up in your double life?”

The lyrics also allege that Harbour, 50, is a “sex addict” and accuses her partner of having a “double life,” despite having an open marriage.

Although “P—y Palace” has some of the most shocking lyrics, the entire album — which is her first release in seven years — is seemingly inspired by the downfall of her marriage to the “Stranger Things” star.

In another song “Tennis,” she describes confronting her husband over texts with a woman named Madeline, wanting to know whether “it was just sex, or is there emotion?”

Allen went on to specify the “arrangement” in her union, which was, “Be discreet and don’t be blatant / There had to be payment / It had to be with strangers.”

Since the album’s release, the so-called “Madeline” has been revealed to be Natalie Tippett, a costume designer who met Harbour while filming a movie in New Orleans in 2021, and the two allegedly ended up having an affair.

“Of course I’ve heard the song,” Tippett told the Daily Mail last week while reportedly rolling her eyes.

“But I have a family and things to protect. I have a 2-and-a-half-year-old daughter, and I understand this is going on,” the single mom added. “It’s a little bit scary for me.”

The “Smile” hitmaker spoke about the “betrayal” her album is centered around in a Perfect Magazine interview, published Tuesday.

“There are definitely some things that happened in my real life that are reflected on this record,” she revealed.

“Two people who were once together are not together. And that’s really sad. It’s hard. It’s hard for me to not have my person, you know?”

News of Allen and Harbour’s separation broke in February after months of breakup speculation. That same month, the musician checked herself into a treatment center for “emotional turmoil.”

She officially filed for divorce last month after five years of marriage.

Despite Allen airing out her messy split from Harbour through her new album, the actor has yet to address their breakup publicly and has done his best to actively dodge questions about it.
