Lily Allen released her new album, West End Girl, on October 24, 2025. In the songs, which are loosely "inspired" by things the singer experienced in her marriage with Stranger Things actor David Harbour (who she split from in December 2024), Lily talks about being jealous of this woman and alludes to an open marriage. In 'Tennis' she sings: "So I read your text, and now I regret it/ I can't get my head 'round how you've been playing tennis / If it was just sex, I wouldn't be jealous / You won't play with me and who's Madeline?" In 'Madeline', the 40-year-old, goes a little deeper, saying: "How long has it been going on? Is it just sex or is there emotion?/ He told me it would stay in hotel rooms, never be out in the open." Following the album drop, fans began speculating who this mysterious woman might be. And it wasn't long before a face was put to the name, with costume designer Natalie Tippett claiming she had an affair with David Harbour. Natalie, 34, is a costume designer from New Orleans and is said to have met David, 50, in 2021 while on the set of Netflix's We Have A Ghost, in which he played the lead. According to reports, their alleged affair began shortly after filming began and Harbour reportedly flew Tippett to his home in Atlanta once production wrapped. In an exclusive interview with Daily Mail, Natalie confirmed that she'd heard the lyrics from Lily's new album. She said: "Of course I've heard the song. But I have a family and things to protect. I have a two-and-a-half-year-old daughter, and I understand this is going on. It's a little bit scary for me." When asked if she was aware that her private texts had been used in the new music, She replied: "Yeah. I just don't feel comfortable talking about it at the moment."
