Charli XCX was among the guests at the wedding of Matty Healy, the frontman of The 1975 and former boyfriend of Taylor Swift, to model Gabbriette Bechtel. The ceremony took place at Castillo del Lago in Los Angeles.

Healy and Bechtel exchanged vows as the sun set, with the venue previously owned by Madonna. Charli XCX, who is married to The 1975's drummer George Daniel, was seen in a floor-length black gown with a thigh-high split. Other notable attendees included influencers Stassie Karanikola and Devon Lee Carlson, and actor Duke Nicholson.

The attendance of Charli XCX at the wedding has drawn attention due to the reported deterioration of her relationship with Taylor Swift. The two artists, who were once friends and collaborators, are rumored to have written diss tracks about each other. Swift brought Charli XCX on as a support act for her 2018 Reputation stadium tour, performing together on more than 50 dates.

However, their relationship is thought to have soured after Swift's split from Healy in June 2023. Shortly after, Healy was seen in a public display of affection with Bechtel. Healy and Bechtel announced their engagement in 2024, following a nine-month courtship. A source suggested that Healy and Bechtel began dating around the same time Swift and Travis Kelce became public with their romance.

Charli XCX's presence at Healy's wedding contrasts with her absence from Swift's recent wedding to Travis Kelce in New York. The former tour mates' apparent falling out has been a subject of discussion, with speculation that lyrics in Swift's recent album, "The Tortured Poets Department," refer to Charli XCX. Swift described one song, "Actually Romantic," as a "love letter to someone who hates you," and noted that the subject had an "adversarial relationship" with her that she was unaware of.

Lyrics from "Actually Romantic" appear to reference Charli XCX's perceived drug use and her friendship with Healy. One line, "High-fived my ex and then you said you're glad he ghosted me / Wrote me a song saying it makes you sick to see my face," is interpreted as a jab at Charli XCX's connection to Healy. Swift stated the song was about realizing someone else had a one-sided, adversarial relationship with her.

Meanwhile, Charli XCX is rumored to have addressed Swift in her song "Sympathy Is A Knife" from her album "Brat." The lyrics include lines such as "Don’t wanna see her backstage at my boyfriend’s show" and "Fingers crossed behind my back / I hope they break up real quick," suggesting a strained dynamic.

Charli XCX previously spoke about opening for Swift on the Reputation tour, telling Pitchfork in 2019 that it felt like "waving to 5-year-olds" and that she decided to stop opening for other artists. She later clarified her remarks, expressing gratitude to Swift and explaining that performing for all-ages audiences was new to her after playing 18+ club shows.
