Calvin Harris isn’t thrilled with Taylor Swift after their breakup. The Scottish DJ went on Twitter and accused his ex-girlfriend of trying to bring him down after reports regarding the cause of their split surfaced Wednesday.

Swift’s rep confirmed suspicions that she co-wrote Harris’ latest hit, “This Is What You Came For,” under the name Nils Sjoberg, according to Billboard. The initial reports, however, also claim that this is what caused the couple’s split.

When Ryan Seacrest asked Harris about working with his then-girlfriend, Harris lied and said they’d never discussed it. “You know we haven't even spoken about it. I can't see it happening though,” he said. TMZ reports that the “Shake It Off” singer felt “disrespected,” and the interview led to the downfall of their relationship.

The only thing Swift’s rep confirmed is the fact that Swift used the pseudonym Nils Sjoberg, but Harris seems to feel that the revelation reflects poorly upon him. He accused his ex of trying to pit audiences against him and creating a Katy Perry-like feud.

First, Harris confirmed that she not only wrote the lyrics, but her voice is on the track as well. He complimented her talents and noted that she was the one who wanted to keep her involvement a secret.

The “I Need Your Love” producer didn’t stop there, though. He went on to accuse Swift and her team of trying to villainize him. “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 said.

He also mentioned Swift’s highly publicized new relationship with “Thor” actor Tom Hiddleston. “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 added.

He seemed to imply that Swift was manipulating the press out of boredom. Harris also compared himself to pop singer Katy Perry in another tweet and said Swift should focus on the positive things in her own life.

This isn’t the first sign that Harris is unhappy with his ex. Earlier this month, Page Six reported that Harris was “hurt” that Swift moved on so fast and those close to him feel the “Wildest Dreams” singer “manipulated” the relationship. “Looking back, some friends do feel like Taylor’s team manipulated and orchestrated part of [her] relationship [with Calvin] after seeing how public she is with her new guy,” a source said.
