The rapper also reveals what it's really like to work with Beyonce.
Kendrick Lamar wants no part of the feud between Taylor Swift and Katy Perry, despite collaborating with Swift on her 2014 track, "Bad Blood."
The 30-year-old rapper covers the latest issue of Rolling Stone, and reveals whether he knew that "Bad Blood" was most likely about Perry. "No, I wasn't aware of that, bro," he says. "On the record, no. Which makes it even more funny now, for sure. That's far beyond my concern."

Lamar quips, "I have to stay away from that, for sure. That's some real beef."
After collaborating with Swift, he went on to work with Beyonce on her song, "Freedom," which was featured on the acclaimed album Lemonade. The hip-hop star says he learned from Queen Bey "how particular to be about your music."
"She's a perfectionist," he notes, calling attention to his performance with Beyonce at the 2016 BET Awards. "Think about the BET performance. She was very particular -- the lighting, the camera blocking, the transition from the music to the dancing. It was confirmation of something I already knew."
Lamar also admits that he's a huge fan of Beyonce's husband, JAY-Z. "That was my guy. Still is. I'm still a fan," he says when asked about the 47-year-old rapper. "That was just a page I took out of his book, to be able to carry a lyric through conversation and make it feel like I'm sitting right here talking to you."

Lamar seems to be in Bey and Jay's inner circle, but he still didn't get invited to join them at a SoulCycle class in Santa Monica, California, on Tuesday. Kelly Rowland, however, did work out with the power couple! Check it out:
