Just in: Donald Trump declares ‘I hate Taylor Swift’ after she endorses Kamala Harris..

He’s got bad blood.

Donald Trump shared his distaste for American sweetheart Taylor Swift after she endorsed Kamala Harris in the 2024 presidential election.

“I HATE TAYLOR SWIFT!” the former president, 78, wrote on his social media platform, Truth Social, on Sunday.

Reps for the 14-time Grammy winner weren’t immediately available to Page Six for comment.

I think she is a steady-handed, gifted leader and I believe we can accomplish so much more in this country if we are led by calm and not chaos,” the “Lover” songstress, 34, added.

“I was so heartened and impressed by her selection of running mate @timwalz, who has been standing up for LGBTQ+ rights, IVF, and a woman’s right to her own body for decades.”

Swift also addressed a recent AI image of herself “falsely” endorsing Trump.

Swift also addressed a recent AI image of herself “falsely” endorsing Trump.

It really conjured up my fears around AI, and the dangers of spreading misinformation,” she added, explaining the fabricated image pushed her to be transparent about who she will vote for.

The pop star encouraged her fans to review both candidates’ policies and conduct proper research before choosing who they would support.

Swift signed the lengthy post from a “Childless Cat Lady,” referencing Trump’s running mate JD Vance’s controversial comments about women who dont have kids.

Trump quickly responded to the “Cruel Summer” songstress’ post, telling “Fox & Friends” that he likes Swift’s BFF Brittany Mahomes “much better.”

“She’s a big Trump fan,” he said.

Mahomes, 29, has not shied away from her support for Trump on social media.

Trump later retaliated to Swift’s support for Harris by using her Era’s Tour T-shirt design to release new campaign merchandise.

The original T-shirt is a black-and-white design, showing the pop icon in the middle of her various studio albums and reading, “Taylor Swift The Eras Tour.”

Trump’s version stole Swift’s design but instead replaced her photo with snaps of himself and the slogan, “Make America Great Again.”
