Kid Rock just blasted Taylor Swift for being a Democrat.

The musician, who's a longtime Republican and Donald Trump supporter, took to Twitter on Friday (August 9) to slam the "You Need to Calm Down" singer for her political views, as well as insinuate her intentions are calculated and that she only leans left because she wants to be in Hollywood movies. As most fans know, the Swift is set to star in the upcoming film adaptation of Cats, which is expected to hit theatres later this year.

"Taylor Swift wants to be a democrat because she wants to be in movies….period. And it looks like she will suck the doorknob off Hollyweird to get there. Oldest move in the book. Good luck girl," Kid Rock wrote.

It's unclear what prompted his public outburst, it could be because of the pop's star political comments during her candid new Vogue interview. In it, she discusses why she never spoke up during the 2016 elections.

“Unfortunately in the 2016 election you had a political opponent who was weaponizing the idea of the celebrity endorsement," she said. "He was going around saying, 'I’m a man of the people. I’m for you. I care about you.' I just knew I wasn’t going to help. Also, you know, the summer before that election, all people were saying was 'She’s calculated. She’s manipulative. She’s not what she seems. She’s a snake. She’s a liar.'"

"These are the same exact insults people were hurling at Hillary [Clinton]. Would I be an endorsement or would I be a liability? Swift continued. "'Look, snakes of a feather flock together. Look, the two lying women. The two nasty women.' Literally millions of people were telling me to disappear. So I disappeared. In many senses."
