A judge on Monday dismissed Justin Baldoni’s $400 million defamation lawsuit against Hollywood power couple Blake Lively and Ryan Reynolds, a major development in the ongoing civil litigation between former co-stars Lively and Baldoni.

But on June 9, Judge Lewis J. Liman threw out Baldoni's lawsuit, ruling that the statements at the center of the suits were either privileged or lacked the necessary legal basis for defamation. Baldoni's team may amend certain claims and refile by June 23.

A US judge dismissed Justin Baldoni's entire $US400 million ($613 million) lawsuit against Blake Lively and her husband Ryan Reynolds, but that doesn't guarantee the drama surrounding the It Ends With Us co-stars is over.
