Calvin Harris tweets candidly about Taylor Swift post-breakup

Calvin Harris has a thing or two to say about ex-girlfriend Taylor Swift, and he's not afraid to use Twitter to say them.

Harris tweeted out a response Wednesday to People magazine breaking the news that Swift helped write Harris' latest hit with Rihanna, "This is What You Came For."

Harris confirmed the story, and started out with a very professional and nicely worded message about his famous ex. "And she sings on a little bit of it too," he wrote. "Amazing lyric writer, and she smashed it as usual."

But then the Scottish DJ and producer apparently decided he had some more things about Swift that were worth sharing, as he continued on.

Swift's ears must be burning.
