Songfacts®:

• "Tennis" is a track from Lily Allen's 2025 album West End Girl, which was inspired by the breakdown of her marriage to actor David Harbour. Allen warned us the record was autofiction, not autobiography. It is the kind of disclaimer that suggests everything is true except the bits that might get someone's lawyer involved.
• The song starts in a kitchen, where Allen is making her partner's favorite meal, only to find him emotionally distant. The tension escalates when he defensively grabs his phone back from her hands after showing her an Instagram post, prompting Allen to investigate further. From there, she plays detective, and unlike another Allen song about betrayal, "Smile," nobody gets a happy ending.
• "Playing tennis," in Allen-speak, is a metaphor for a supposedly negotiated open relationship, except one partner is playing by Wimbledon rules and the other is playing Mario Tennis with emotional save files. Allen was prepared to accept casual encounters; what she can't stomach is discovering on his phone that Harbour has a genuine emotional involvement with another woman named Madeline.
• "Tennis" ends with Allen repeating the mantra "Who's Madeline?" and if you think that sounds like a setup for something, you'd be right. The very next track on the album is "Madeline," which is the moment when the camera pans from the cheating partner to the other woman.
• Two days after the release of West End Girl, The Daily Mail revealed that Madeline was Natalie Tippett, a Netflix costume designer who met David Harbour in 2021 on the set of We Have A Ghost. Their alleged affair reportedly kicked off shortly thereafter.
• While this all sounds like an HBO limited series, West End Girl came together with almost suspicious efficiency. Allen made the record in 10 days at producer Blue May's Los Angeles home.
  
  "I was with the executive producer, this guy called Blue, who was also the musical director on my last tour in 2018," Allen told Interview magazine. "I was here in New York and I was like, 'I'm going f---ing crazy. I need to get out of this house and write with somebody I trust.' I called up Blue and he had 10 days so I just did it in those 10 days."
  
  No writer's retreats. No vision boards. Just tea, trauma, and a keyboard.
• Allen and May, together with co-executive producer, Kito, formerly of Diplo's Mad Decent universe, produced all the album's tracks. They put together a rotating writing squad - Hayley Gene Penner, Chloe Angelides, and Violet Skies - who came and went over the 10 days.
  
  Chloe Angelides, who co-wrote "Tennis" with Allen, brought pop credentials that include Selena Gomez' "Fetish" and Katy Perry's "Woman's World."
