Blake Lively and husband Ryan Reynolds told a federal judge Thursday that they will seek to dismiss Justin Baldoni’s defamation lawsuit. Attorneys for the two sides are due in court Monday for the first hearing on the megafeud between the two “It Ends With Us” co-stars.

Baldoni previously accused his It Ends With Us costar of trying to "destroy" him with false allegations of sexual misconduct

Baldoni, in a lawsuit filed in New York federal court on Thursday, alleges extortion, defamation and claims related to breach of contract, among several others. He’s joined by his film studio, Wayfarer, and its chief executive Jamey Heath, and their public relations representatives, Melissa Nathan and Jennifer Abel. They seek at least $400 million.
