Taylor Swift fans set social media alight after she took to Instagram to endorse Kamala Harris following the presidential debate on Tuesday.

The 34-year-old pop superstar branded herself a ‘childless cat lady’ — a reference to widely criticized remarks from Republican Presidential Nominee Donald Trump’s running mate JD Vance — which inspired numerous social media users to get behind her.

‘Childless cat ladies unite!’ wrote one user on X (formerly Twitter) in response to Swift’s surprise endorsement.

To underscore the jab, she posed with her fluffy Ragdoll cat Benjamin Button.

Her social media post garnered praise from fans after some Swifties took Taylor to task for cozying up to her friend Brittany Mahomes, despite her support for Donald Trump.

After noting that she had watched Tuesday night’s debate between Harris and Trump, she explained that she was publicly endorsing Harris to clarify her position after AI-generated images that falsely claimed she had endorsed Trump were spread across the internet.

‘I will be casting my vote for Kamala Harris and Tim Walz in the 2024 Presidential Election,’ she declared.

Swift added that she was supporting Harris ‘because she fights for the rights and causes I believe need a warrior to champion them,’ and she praised her runningmate Walz for ‘standing up for LGBTQ+ rights, IVF, and a woman’s right to her own body for decades.’

Although Taylor’s post seemed to be a hit with her fans, it was also well received by fellow celebrities on Instagram who rushed to give it a ‘like.’

Among the stars giving Swift’s post a thumbs up were Jennifer Aniston, Blake Lively, Demi Lovato, Mindy Kaling, Ashley Tisdale, Chrissy Teigen and her husband John Legend, Lupita Nyong’o, Molly Sims, Kristin Davis and Andy Cohen.

Oprah liked the post, as did Swift’s pals Selena Gomez, Suki Waterhouse and Karlie Kloss.

Other stars sharing their approval included Christie Brinkley, Olivia Wilde, Lili Reinhart, Jennifer Garner, Michelle Pfeiffer, Lady Gaga, Kerry Washington, Mandy Moore, Rachel Zegler, Ellen DeGeneres, Quinta Brunson, Charli XCX, Aubrey Plaza, Lisa Rinna, Katie Holmes and Maren Morris.

Several Swifties who reacted positively to the pop star’s endorsement were of the opinion that it was the final push Harris needed to push her over the finish line.

‘OMG!!’ wrote another excited fan while including a gif of Taylor cheering that read, ‘Let’s go!’ They added the hashtag #TaylorSwiftforHarrisWalz.

Others imagined Swift celebrating after shaking up the campaigns with her endorsement.

One user edited the popular ‘disaster girl’ meme to replace the devious-looking child with Swift as a house was engulfed in flames behind her.

Another person reposted Taylor’s ‘Childless Cat Lady’ line with a clip of a woman screaming with joy as she created a makeshift flamethrower.

Robert Griffin III joked, ‘Oh it’s over. Swifties don’t play.’

Desus Nice joked that ‘we aint seeing kid rock an any tortured poet department rerelease’ in the wake of the endorsement.

One user wrote that the ‘debate was so devastating for Trump that it expedited the Taylor Swift endorsement.’

Others alluded to reports that the Trump campaign was dismayed by how JD Vance’s past statements have come to haunt it.

‘trump is going to hang jd vance by his ankles off the top of trump tower,’ joked a poster on X.

Swift’s endorsement appears to have shored up her support from many fans who previously criticized her for continuing her friendship with Brittany Mahomes.

The pop star befriended Mahomes, who is married to Kansas City Chiefs quarterback Patrick Mahomes, after she began dating his teammate, tight end Travis Kelce.

Brittany was previously a member of Taylor’s ‘squad’ of famous female friends, but it wasn’t clear if her position was safe after she liked several pro-Trump social media posts, which outraged the Shake It Off singer’s fans.

There were rumors of a rift between the two, particularly after Brittany wasn’t among Taylor’s entourage when the Chiefs played the Ravens earlier this month.

However, a source later told The Sun that the two simply had different plans for that game.

Taylor then indicated that she and Brittany were still pals when they shared an affectionate hug at the Men’s Singles Final match at the US Open on Sunday.

Some Republicans — and even Swifties — had speculated that the songstress might not endorse a candidate after previously endorsing President Joe Biden in the 2020 election.

Her renewed embrace of Mahomes fueled the fringe theory, but Tuesday’s post-debate endorsement made it clear that Swift’s politics and values were unchanged.

One X user mocked the idea that she was ‘soft-launch[ing] becoming a Republican’ by simply reposting her forceful endorsement.

Swift’s embrace of Mahomes, coupled with her endorsement, instead suggests she’s able to maintain friendships with conservatives, even as she rejects Donald Trump.
