Talk about passive aggressive: Taylor Swift completely ignored ex-boyfriend Calvin Harris when he unleashed a viral Twitter rant Wednesday. The music producer was irked after Swift’s reps issued a statement following their confirmation that she wrote the lyrics for “This Is What You Came For.” She was apparently ticked off when Harris said in an interview that he didn’t think they would work together in the future.

“I wrote the music, produced the song, arranged it and cut the vocals though. And initially she wanted it kept secret, hence the pseudonym,” he wrote on Twitter. “Hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage though.”

He then addressed Tom Hiddleston, who Swift began dating days after their breakup. “I figure if you're happy in your new relationship you should focus on that instead of trying to tear your ex bf down for something to do,” he said. “I know you're off tour and you need someone new to try and bury like Katy ETC but I'm not that guy, sorry. I won't allow it.”

Harris finished his rant on a high note. “Please focus on the positive aspects of YOUR life because you've earned a great one,” he wrote. “God bless everyone have a beautiful day.”

Harris’ messages garnered thousands of likes from his 7.83 million followers. Naturally, the one where he referenced Swift’s new relationship got the most attention, earning nearly 70,000 likes and more than 40,000 shares.

Even singer Katy Perry chimed in. She has a famous feud with the “Bad Blood” singer and discretely acknowledged Harris’ statements by posting a gif of presumptive Democratic presidential candidate Hillary Clinton rolling her eyes.
