Don't say we didn't, say we didn't warn you, Diplo.

As the Daily Mail points out, the 36-year old DJ says he made the "biggest mistake" of his career when he called Taylor Swift fans, aka "Swifties," the "worst people in the world."

"You can't step into that arena," he tells GQ Style of T. Swift's legion of die-hards. "That was something I was never prepared for … one of the biggest mistakes of my career was definitely f---ing with her."

The "Where Are U Now" remixer then proceeded to put his foot in his mouth again, reportedly comparing Swifties to the North Korean army.

"It's like an army that's worse than North Korea," he is quoted as saying. "All I know is don't ever get into a feud with Taylor Swift. She has like 50 million people that will die for her."

Diplo and Taylor appeared to have buried the hatchet — remember that cute Grammys Instagram snap? — after the DJ said the "Shake It Off" singer needed a "booty." But we doubt her fans will be just as forgiving the second time around.
