LOS ANGELES (AP) — “It Ends With Us” actor and director Justin Baldoni has sued his co-star Blake Lively and her husband, “Deadpool” actor Ryan Reynolds, for defamation and extortion on Thursday in the latest move in a bitter legal battle surrounding the dark romantic drama.

The lawsuits surrounding It Ends With Us keep making headlines.

Escalating his litigiousness, Baldoni has sued Lively and her husband Ryan Reynolds for $400 million, alleging that the power couple stole control of Baldoni's film as a director and orchestrated an effort to destroy his career and reputation with what he's referring to as false allegations of sexual assault.

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.

The "Deadpool" franchise is named in Justin Baldoni's new lawsuit against "It Ends With Us" costar Blake Lively and her husband Ryan Reynolds. Here's why.

Baldoni and Lively have been at odds since the now-endless It Ends With Us press tour, after which rumors of sexual harassment allegations spilled into the press. By the end of Us, Baldoni had filed suit against the Times for its bombshell story accusing him of harassing Lively and orchestrating a smear campaign against him.

Ryan Reynolds is one of the stars to have invested in Colombian soccer team La Equidad—a deal that was announced the same day as Justin Baldoni’s lawsuit against the Deadpool star and Blake Lively.

The popstar and her parents dined out in downtown Manhattan Friday, one day after she was named in Justin Baldoni’s $400 million lawsuit against Blake Lively and Ryan Reynolds.

"It is not strange that Ryan Reynolds was named in light of Baldoni's theories in the complaint," a defamation attorney tells Yahoo Entertainment.

Ryan Reynolds has announced he is investing in another football club, with the significant business move coming the same day it was revealed that he and his wife Blake Lively are being sued for $400m by her It Ends With Us director Justin Baldoni.
