Charli (referring likely to Charli XCX, the singer, rather than Charli D'Amelio) has expressed complex feelings about Taylor Swift publicly. Charli XCX has acknowledged opening for Taylor on her "Reputation" tour and expressed gratitude for the opportunity; however, she also made a comment that performing for Taylor's audience felt like "waving to 5-year-olds," which stirred some controversy and was later clarified as not intended to throw shade but to describe a different energy on stage than she was used to.

Charli XCX's song "Sympathy Is a Knife" has been widely interpreted by fans and commentators as referencing Taylor Swift, portraying feelings of insecurity and jealousy triggered by Taylor. The song contains lyrics that some believe indirectly criticize or reflect on Taylor's behavior or presence in Charli's life, especially regarding backstage dynamics and emotional struggle. Some interpretations suggest the song addresses a complicated mix of admiration, rivalry, and personal reflection rather than outright hostility.

Despite some public speculation and fan theories suggesting tension, Charli XCX also condemned negative fan behavior towards Taylor Swift and called for respect among communities. There is no confirmed direct feud, and Taylor Swift herself has praised Charli's songwriting and even danced to her performances recently, indicating no visible animosity from Taylor’s side.

In summary, Charli XCX has spoken about Taylor Swift with a mixture of nuanced respect, personal reflection on insecurities triggered by Taylor, and colorful commentary about the experience of touring and interacting with Taylor’s fan base and persona, but she denies any malicious intent or direct hostility. The situation remains more complex than a simple feud and includes elements of artistic expression and public perception.
