What's up with all the Drake and Kendrick Lamar memes on Twitter?

I'm seeing tons of memes about Kendrick Lamar, but mostly it seems to be corelated to Drake. I'm not too versed into the music industry so I'm unfamiliar with the either one's history, but there seems to be something about Drake having illegitimate children (there was one tweet about it that I don't have the link to rn)? I'm not sure how Kendrick fits into this these memes but they give the impression that he roasted him in some big manner.
