The behind-the-scenes drama between “It Ends With Us” co-stars Blake Lively and Justin Baldoni has escalated into one of Hollywood’s most contentious legal battles.

"It Ends With Us," star Blake Lively alleges her female co-stars were also uncomfortable with Justin Baldoni's behavior, a new court filing claims.

Blake Lively's publicist, Leslie Sloane, argued it was not defamatory to say that the whole cast of "It Ends With Us" hated director Justin Baldoni.

Blake Lively alleged she was not the only woman concerned about Justin Baldoni's "unwelcome and uncomfortable behavior."

In an amended complaint, attorneys for Blake Lively added nearly 50 pages to their lawsuit against the actress’ co-star Justin Baldoni, furthering the details to Lively’s initial allegations of sexual harassment and retaliation.

"The amended complaint has also added a new claim for defamation based on the repeated false statements the defendants have made about Ms. Lively," her lawyers tell TheWrap

In the amended complaint, Ms. Lively said that Mr. Baldoni, her co-star in “It Ends With Us,” made two other actresses on set uncomfortable and that they were willing to testify.
