'Boo!' Kesha becomes the latest celebrity to take on J.D. Vance comments

J.D. Vance has picked up another celebrity antagonist with his dismissive remarks about "childless cat ladies."

Pop singer Kesha reproached the Republican vice presidential candidate for saying "miserable" childless women ran the U.S. to "make the rest of the country miserable, too," when a paparazzo stopped her Thursday at Los Angeles International Airport to ask her about Donald Trump's running mate, reported Page Six.

“Boo! F--- that man!" Kesha told the photographer, according to video obtained by TMZ. "That’s all I have to say: F--- them all."

The paparazzo then asked whether the 37-year-old singer believed the country was led by “childless cat ladies,” and she said, "It is, b----," before agreeing that Vance's comments were "absolutely" sexist.

Actress Jennifer Aniston, who rarely makes political statements, also spoke out against Vance's remarks about women who hadn't had children, saying she hoped the Ohio Republican's daughter would be "fortunate enough to have children of her own one day."

"I truly can’t believe this is coming from a potential VP of the United States,” the "Friends" star wrote on her Instagram page.

Taylor Swift fans have also mobilized against Trump's running mate, and conservative commentator Meghan McCain warned that Vance would be an election problem for Republicans.

“I have been trying to warn every conservative man I know — these JD comments are activating women across all sides, including my most conservative Trump supporting friends," McCain said.
