Kendrick Lamar's Rolling Stone interview has just been released and in it he touches on the great beef of our time: Katy Perry vs. Taylor Swift.

Back in 2015, K.Dot jumped on a remix of Swift's Bad Blood, a song all about her relationship with Perry, and he even appeared in the video.

Now he's said that he had absolutely no idea that the song was about a beef.

"No, I wasn’t aware of that, bro," he said, laughing.

"That’s a great question. No! On the record, no. Which makes it even more funny now, for sure. That’s far beyond my concern. I have to stay away from that, for sure. That’s some real beef."

It's very funny given that it was the song that basically fuelled two years of beefing before Katy Perry addressed it this year and said she was willing to put it behind her.

You can read the full interview here in which he talks about Trump, ghost writing and Drake.
