Lily Allen Flaunts Her Thong in a Naked Dress After David Harbour Split

Lily Allen is in her revenge era.

Allen, 40, showed off her figure in a sheer dress at the Hunger Games: On Stage premiere on Wednesday, November 12, amid headlines surrounding her split with husband David Harbour.

While striking a pose on the red carpet, the singer stunned in a vintage 1999 Dior crochet dress featuring long sleeves and a semi-sheer silhouette. Underneath her floor-length skirt, she wore nothing but a thong. Allen let her risque look speak for itself, opting for minimalistic jewelry, including silver rings.

Allen made her ensemble even hotter with smokey eyeshadow and long lashes. She completed her glam with dewy skin, bronzed cheeks and lined, glossy lips. Her black hair was pulled back into a messy — but chic — updo with her baby bangs parted over her forehead.

Allen’s sexy getup comes after she released her new album, West End Girl, about her messy divorce from Harbour, 50.

“I don’t feel like I’m being mean. It was just the feelings I was processing at the time,” she told Interview magazine at the time.

She added, “I feel very differently about the whole situation now. We all go through breakups, and it’s always f***ing brutal. But I don’t think it’s that often that you feel inclined to write about it while you’re in it.”

Throughout the album, Allen details a relationship, starting with a move to New York City together, which ended with her moving back to her native London shortly after.

After returning to her apartment, Allen claimed she saw a text from a woman named Madeline in Harbour’s phone.

“How long has it been going on? Is it just sex or is there emotion?” she sang in her song titled Madeline.

Her album progressed to calling an ex a “sex addict,” and she sang about an open relationship that “went astray.”

The Stranger Things actor has not yet commented on Allen’s album. He briefly opened up about their relationship in April, telling British GQ, “I’m protective of the people and the reality of my life.” He added, “There’s no use in that form of engaging [with rumors] because it’s all based on hysterical hyperbole.”

Allen previously had another naked look earlier this month, while posing on the red carpet during the 2025 CFDA Fashion Awards in New York City.

For the event, she wore a lingerie look by Colleen Allen, featuring a white bralette that barely covered her chest. The lingerie was complete with lace embellishments and thick straps. She styled the number with a low-waisted column skirt, adorned with the same lace details on her sides.

Lily covered up with a delicate white cape, which she complemented with an elegant updo and dainty dangling earrings.

Her makeup was just as elegant, with black eyeliner, soft eyeshadow and a touch of mascara. She topped off her glam with manicured brows, blushed cheeks and pink lips.
