Justin Baldoni has receipts.

The “It Ends With Us” actor and director, 41, launched a new website over the weekend with alleged unseen texts between himself and his co-star Blake Lively, who is suing him for sexual harassment, and her husband, Ryan Reynolds.

The site, called Lawsuit Info, links to an amended version of his $400 million suit against Lively, 37, Reynolds, 48, and their publicist Leslie Sloane. Baldoni is accusing the trio of defamation and extortion.

Baldoni’s website also links to a 168-page document outlining the timeline of events surrounding the filming of “It Ends With Us,” which he filed in court with his complaint.

It includes never-before-seen texts and emails that Baldoni allegedly exchanged with Lively and Reynolds, who, according to Baldoni, steamrolled him during the making of the movie.

One of the messages between Baldoni and Lively from April 2023 shows them discussing a rewrite for the film’s rooftop scene. Lively allegedly wrote to her co-star, “If you knew me (in person) longer you’d have a sense of how flirty and yummy the ball busting will play. It’s my love language. Spicy and playfully bold, never with teeth.”

In another text from the same month, Baldoni told Lively he could set her up with an intimacy coordinator whom he hired for the film. In response, Lively wrote, “I feel good. I can meet her when we start :) thank you though!”

Two months earlier, Reynolds told Baldoni that he “adores” him in a text message.

“I’m excited for you to work together,” the “Deadpool” star wrote to Baldoni. “I’m excited for Blake to crack open her creative piggy bank with someone as dynamic as you. This is gonna be INCREDIBLE … I happen to adore you, Justin.”

In June 2023, Lively allegedly texted Baldoni to invite him to her trailer to go over their lines.

“I’m just pumping in my trailer if you wanna work on our lines,” Lively wrote to Baldoni, according to the screenshotted texts, referring to using a breast pump. Baldoni replied, “Copy. Eating with crew and will head that way.”

The Post has reached out to reps for Lively and Reynolds for comment.

In his lawsuit, Baldoni accused Reynolds of using the character Nicepool in “Deadpool & Wolverine” as a “transparent and mocking portrayal of Reynolds’ warped perception of Baldoni.”

Baldoni claimed that the Nicepool scene was shot after an “ambush” at Reynolds and Lively’s apartment, where Reynolds allegedly berated Baldoni and demanded he apologize for things that Baldoni insisted he didn’t do.

Baldoni launched his website to refute Lively’s claims that he sexually harassed her on the set of the film.

In December 2024, Lively sued Baldoni, his production company Wayfarer Studios, his producer James Heath, his publicist Jennifer Abel, crisis publicist Melissa Nathan and more. In addition to her sexual harassment claims, she accused Baldoni and his team of orchestrating a p.r. smear campaign against her.

Baldoni, who has denied all of Lively’s claims, countersued Lively, Reynolds and their publicist on various claims including civil extortion, defamation and false light invasion of privacy.

The “Jane the Virgin” actor is also suing the New York Times for $250 million for libel and false light invasion of privacy, after the newspaper released an article detailing Lively’s sexual harassment claims and how Baldoni’s team allegedly tried to “tarnish” her image.

Lively and Baldoni are headed to trial on March 9, 2026.
