Taylor Swift just endorsed Harris and Walz. Now Elon Musk is trying to pick a fight with her.

Fine Taylor you win I will give you a child and guard your cats with my life,” Musk wrote in an X post on Wednesday morning.

Musk was weighing in on Swift’s latest Instagram post, in which she endorsed Harris.

Swift posted her endorsement on Tuesday night, shortly after Harris completed her first presidential debate with former President Donald Trump.

I will be casting my vote for Kamala Harris and Tim Walz in the 2024 Presidential Election. I’m voting for @kamalaharris because she fights for the rights and causes I believe need a warrior to champion them,” Swift wrote in her post.

“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,” she continued, before signing off with the label “Childless Cat Lady.”

The term appeared to be a dig at Trump’s running mate, Sen. JD Vance of Ohio, who made remarks about childless people during a Fox News interview in 2021.

We are effectively run in this country via the Democrats, via our corporate oligarchs, by a bunch of childless cat ladies who are miserable at their own lives and the choices that they’ve made, and so they want to make the rest of the country miserable too,” Vance said then.

Representatives for Swift and Musk didn’t immediately respond to requests for comment by Business Insider sent outside regular business hours.

At press time, Swift had not responded to Musk’s X post.
