MUMBAI: American DJ Diplo has a suggestion to make -- he says getting into a feud with Taylor Swift would be a bad idea for anyone.

Having faced the wrath of the legions of her fans in November, when he called upon his own fans to start a campaign to get Swift a "booty", he now admits making the Twitter comments was one of his "biggest mistakes", reports femalefirst.co.uk.

The Grammy-nominated musician, who dated Swift's pop rival Katy Perry last year, told GQ Style magazine, "I can go head-to-head with anybody. I don't care who you are."

"I didn't go after Lorde because she's my friend and she's a young girl and the one person I kept it cool with. 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."

"It's like an army that's worse than North Korea. You can't step into that arena. That was something I was never prepared for... one of the biggest mistakes of my career was definitely f***ing with her."

Swift's fans are otherwise known as 'Swifties'.
