Who’s afraid of a little old courtroom?

Taylor Swift has reportedly been subpoenaed in Blake Lively’s high-profile legal battle against her “It Ends With Us” director and co-star Justin Baldoni.

Baldoni’s lawyer, Bryan Freedman, fired off the request for the international pop star, 35, to be a witness in the ongoing legal war, in December, claiming he allegedly sexually harassed her on the film’s set and then spearheaded a smear campaign against her.

The filmmaker denied the accusations and countersued Lively and her husband, Ryan Reynolds, for , accusing the couple of defamation, civil extortion, false light invasion of privacy, and more, which they, too, denied.

Swift’s name came up several times in Baldoni’s lawsuit.

The “Bad Blood” singer has a tight friendship with the famous couple, so tight that she’s the godmother of Lively and Reynolds’ three daughters.

He claimed that Swift was at the couple’s New York penthouse for a pivotal meeting after Lively rewrote the famous “It Ends With Us” rooftop scene.

In the lawsuit, Baldoni alleged the conversation got heated, and he felt ambushed. He also claimed that Lively tried to use her relationship with the Grammy winner to intimidate him.

After the meeting, Baldoni included an alleged text conversation between him and Lively in the legal documents.

“I really love what you did. It really does help a lot. Makes it so much more fun and interesting. (And I would have felt that way without Ryan or Taylor),” Baldoni wrote to the actress, which he later claimed in the suit that he felt “obligated” to say.

In an alleged text message to Baldoni, Lively called herself Khaleesi from “Game of Thrones” and referred to Reynolds and Swift  per the filing.

“If you ever get around to watching Game of Thrones, you’ll appreciate that I’m Khaleesi, and like her, I happen to have a few dragons. For better or worse, but usually for better. Because my dragons also protect those I fight for. So really we all benefit from those gorgeous monsters of mine. you will too, I can promise you,” her alleged text message read.

Swift’s 2020 song, “My Tears Ricochet,” was featured in an “It Ends With Us” scene and the movie’s trailer.

However, Swift’s camp issued a scathing response over the music sensation’s alleged subpoena.

“Taylor Swift never set foot on the set of this movie, she was not involved in any casting or creative decisions, she did not score the film, she never saw an edit or made any notes on the film, she did not even see ‘It Ends With Us’ until weeks after its public release, and was traveling around the globe during 2023 and 2024 headlining the biggest tour in history,” a Swift representative told The Post on Friday.

“The connection Taylor had to this film was permitting the use of one song, ‘My Tears Ricochet.’ Given that her involvement was licensing a song for the film, which 19 other artists also did, this document subpoena is designed to use Taylor Swift’s name to draw public interest by creating tabloid clickbait instead of focusing on the facts of the case.”

The Post reached out to Swift’s rep, as well as Lively and Baldoni’s lawyers, for comment.

Lively and Baldoni’s trial is set for March 2026.
