Here’s what we know so far about the rumors.
Brittany Mahomes started Taylor Swift and Blake Lively feud rumors explained
There is no confirmed evidence that Brittany Mahomes directly started the feud between Taylor Swift and Blake Lively.
However, according to an April 2025 Instagram post by Katie Paulson, an alleged source claimed Brittany shared a rumor during a girls’ trip that Blake Lively tried to initiate an affair with Justin Baldoni. This rumor reportedly fueled tensions between Swift and Lively.
The fallout started at the end of 2024 when Lively and Baldoni entered a legal battle over alleged on-set misconduct and defamation. According to Baldoni’s countersuit, Swift became involved after attending a script meeting at Lively’s New York penthouse. The suit also stated that Lively referred to Swift and Ryan Reynolds as her “dragons,” implying they supported her in the dispute.
Reports from PEOPLE cite a source close to Swift who said the singer was upset about being dragged into the legal matter. The same source claimed, “Blake knew she and Taylor would come back from this at some point,” and added that Swift felt “relieved they were able to recover from this and put it all behind them.”
Social media users widely circulated rumors about Brittany Mahomes’ alleged role, but no verified proof links her to the fallout. The rumors that Swift told Mahomes or visa-versa, remain unsubstantiated.
Swift and Lively’s friendship showed strain during the lawsuit. However, recent updates suggest they are working to mend it. Neither Swift, Lively, nor Mahomes have publicly confirmed the Instagram-based allegations.
