Did Brittany Mahomes start the feud between Taylor Swift and Blake Lively? A viral Instagram post and swirling rumors have reignited public interest in their alleged falling out.
In an April 2025 Instagram post, blogger Katie Paulson cited an unnamed source claiming that during a girls’ trip, Brittany Mahomes shared a rumor alleging Blake Lively tried to start an affair with her It Ends With Us co-star, Justin Baldoni.
If true, it’s likely that Taylor Swift was the one who passed this information to Mahomes. Still, given the lack of confirmation and the ongoing legal dispute between Lively and Baldoni, it’s wise to approach these rumors with caution and not jump to conclusions.

Tensions allegedly rose in late 2024 when Blake Lively and Justin Baldoni became entangled in a legal battle involving claims of on-set misconduct and defamation.
In his countersuit, Baldoni noted that Taylor Swift had attended a script meeting at Lively’s New York penthouse, where Lively reportedly called Swift and her husband, Ryan Reynolds, her “dragons”—a sign of their backing in the conflict. Despite ongoing speculation, there remains no verified evidence connecting Brittany Mahomes to the fallout.
Swift Frustration
Reports suggest that Taylor Swift grew frustrated after finding herself caught in the middle of the legal feud between Blake Lively and Justin Baldoni.
A source close to Swift told People that the singer was upset when she became entangled in the escalating drama. Reflecting on the situation, the source noted, “Blake knew she and Taylor would come back from this at some point.” Fortunately, the reconciliation appears mutual, with the source adding, “[Taylor’s] relieved they were able to recover from this and put it all behind them.”
In summary, while rumors have circulated about Mahomes’ involvement in the Swift-Lively rift, these remain unsubstantiated, and the trio has not confirmed any such claims.
