The Album She’s Promoting: Diving Deep into *West End Girl*

Lily Allen’s performance tonight is intrinsically linked to her latest musical offering, *West End Girl*. Released on October 24, 2025, the album is her first new body of work in seven years and represents a profound shift in her artistic output.

A Vulnerable and Theatrical Masterpiece

*West End Girl* has been lauded by critics for its raw honesty and theatrical flair, with some reviewers calling it a "divorce album that feels like a stage drama unfolding in real time." Allen herself has described the project as her most "vulnerable" work to date, a claim that is supported by the deeply personal and reflective nature of the lyrics. The album’s success, reaching number two on the UK charts, underscores the public’s enduring connection to Allen’s unique brand of sharp, culturally observant songwriting combined with catchy pop hooks.

Anticipated SNL Setlist and Performance Style

While the official setlist for a musical guest on SNL is always kept under wraps until airtime, it is almost certain that Lily Allen will perform two tracks from *West End Girl*. Given the album's buzz, the most likely candidates for her performance tonight include the lead single and the track "Pussy Palace," which was named one of the Best Songs of 2025 by *Consequence*. The theatrical nature of the album also suggests that her performance in Studio 8H will be a highly visual and dramatic event, possibly featuring elaborate staging or costume changes to match the narrative depth of her new songs. This SNL appearance is a crucial promotional stop for Allen as she gears up for her West End Girl Tour, which is scheduled to hit North American dates in 2026. The energy and reception of her live performance tonight will undoubtedly set the tone for the highly anticipated tour, solidifying her status as one of the most compelling singer-songwriters of her generation.

The SNL Debut: Josh O’Connor’s Comedic Challenge

The other half of tonight's dynamic duo, Josh O'Connor, is stepping into the world of live sketch comedy for the first time. Known primarily for his dramatic roles, particularly his Emmy-winning portrayal of Prince Charles in *The Crown*, O'Connor’s hosting gig presents an intriguing challenge.

Promoting *Knives Out Mystery*

O'Connor's decision to host is a strategic move to raise his profile ahead of his major role in the next installment of the popular whodunit franchise, *Wake Up Dead Man: A Knives Out Mystery*. SNL has historically been a launchpad for actors transitioning to new genres, and fans are eager to see how O’Connor’s subtle, nuanced dramatic style translates into the broad, fast-paced world of SNL sketches.

Potential Sketch Concepts

The writers at SNL, under the guidance of Lorne Michaels, are known for leveraging a host's most famous roles. Viewers can likely expect sketches that poke fun at:

• Royal Life: Parodies of *The Crown*, perhaps with O'Connor's Prince Charles interacting with modern-day celebrities or the SNL cast.
• British vs. American Culture: Humorous takes on the differences between the UK and the US, a classic SNL trope.
• *Knives Out* Spoofs: A sketch featuring O'Connor as a new, overly serious detective or a suspect with a ridiculous accent, playing off the success of the Daniel Craig-led film series.

The combination of Lily Allen's fresh, emotionally charged music and Josh O'Connor's fish-out-of-water comedy will make the December 13, 2025, episode a standout moment in the current SNL Season 51. The episode will air live from New York's Rockefeller Center, providing a perfect capstone to the show's December run before the final episode of the year featuring Ariana Grande.
