A federal judge has dismissed most claims in Blake Lively's sexual harassment lawsuit against Justin Baldoni, her co-star and director in the film "It Ends With Us," according to court documents filed this week.

The ruling represents a significant development in the high-profile case, with the judge tossing the actress's sexual harassment claims against Baldoni in what sources describe as a split decision. Only three claims against Baldoni and his production company Wayfarer Studios remain active.

The dismissal comes just weeks before the scheduled trial date of May 18, when the remaining portions of Lively's lawsuit will proceed to court. The case has drawn considerable attention given the profile of both parties involved in the legal dispute.

Lively had filed the lawsuit against Baldoni, who served as both her co-star and director on the romantic drama film. The nature of the remaining claims that will proceed to trial has not been detailed in the court filings.

The legal battle stems from their work together on "It Ends With Us," though specific details about the allegations and the basis for the judge's dismissal of the harassment claims have not been made public. The case is expected to continue with the surviving claims when the trial begins as scheduled in May.
