The lawsuit is the latest legal action in a feud tied to the 2024 film “It Ends With Us,” which starred Ms. Lively and Mr. Baldoni, who also directed the film.

Everything Justin Baldoni has alleged against Blake Lively as the stars' feud plays out—including in a new federal lawsuit filed Thursday.

Lively first revealed her allegations against Baldoni in an interview with the New York Times. The Times was subsequently sued by Baldoni, who accused the newspaper of promissory fraud and breach of implied-in-fact contract in his $250 million lawsuit.
