Blake Lively supported Taylor Swift’s “The Life of a Showgirl” release with a subtle nod.

The “It Ends With Us” actress “liked” the hitmaker’s Thursday Instagram post marking the release of her highly anticipated twelfth studio album.

“I can’t tell you how proud I am to share this with you, an album that just feels so right,” Swift, 35, captioned a glitzy gallery of showgirl-inspired photos on Thursday evening.

“A forever thank you goes out to my mentors and friends Max and Shellback for helping me paint this self portrait. If you thought the big show was wild, perhaps you should come and take a look behind the curtain…The Life of a Showgirl is out now.”

Reps for Lively and Swift did not immediately return Page Six’s requests for comment.

Lively’s surprising gesture of support comes amid speculation that Swift’s track “Ruin the Friendship” is about the apparent fallout of her friendship with the actress.

However, after listening to the lyrics — which center around a high school romance — Page Six confirmed the song is likely not about Swift’s friendship with the “Gossip Girl” alum.

The former friendship — which saw Lively and Swift frequently stepping out for high-fashion evenings on the town — fizzled following Lively’s sexual harassment case against her “It Ends With Us” co-star Justin Baldoni.

Documents obtained by Page Six in September claimed the “Blank Space” hitmaker — who had previously been subpoenaed by Baldoni’s legal team in May, only for the summons to be dropped that month — “agreed” to be deposed in the matter, as the judge extended the deadline for her testimony.

According to documents, Baldoni’s lawyer Ellyn S. Garofalo claimed the testimony would need to be given “during the week of October 20-25 due to Ms. Swift’s preexisting professional obligations.”

Baldoni’s team alleged she would be “unable to do so” before that time, ostensibly due to today’s landmark album release.

The songstress’s attorneys denied she had agreed to testify in a letter to Judge Lewis J. Liman in September.

“My client did not agree to a deposition,” the statement read. “But if she is forced into a deposition, we advised (after first hearing about the deposition just three days ago) that her schedule would accommodate the time required during the week of October 20.”

Attorneys for Lively also seemingly pushed back on the idea that Swift had “agreed” to a deposition in their own filing.

“In this latest effort, the Wayfarer Defendants assert — though, notably, without evidence — that
Ms. Swift has supposedly ‘agreed’ to sit for a deposition sometime between October 20-25 (some three
weeks after the close of fact discovery in this matter),” docs filed by Lively’s lawyers read.

“Yet, even if one were to take the Wayfarer Defendants’ representation at face value, they have not come close to establishing good cause for their requested relief.”

Swift first became involved in the legal battle when Baldoni, 41, included the singer his January counter-lawsuit against Lively, accusing her of extortion and defamation — a response to her lawsuit against him for alleged sexual harassment, breach of contract and retaliation, among other allegations.

Baldoni alleged in documents that Lively seemingly referred to her husband, Ryan Reynolds, and Swift as protective “dragons” who defend her.

A source told us in February that the debacle made Swift feel “used.”

“Taylor really wishes Blake hadn’t dragged her into this whole situation,” the insider told us. They “have been friends for years and Taylor cherishes genuine friendships, but she can’t help but feel used at this point.”

Baldoni’s $400 million countersuit was thrown out by a judge in June, though Lively’s case rages on.
