In one of the biggest beefs in recent hip-hop history, Drake and Kendrick Lamar are feuding — to the point that police were asked about their feud after a security guard was shot outside Drake’s Toronto mansion on Tuesday. But it wasn’t always this way.

Over a decade ago, the pair collaborated on a few songs: On Drake’s 2011 track “Buried Alive Interlude,” on Lamar’s 2012 release “Poetic Justice,” and on A$AP Rocky’s “(Expletive) ’ Problems” that same year.

That didn’t last very long. In 2013, Pulitzer Prize winner Lamar was featured on Big Sean’s “Control,” in which he called out a slew of contemporary rappers including Drake, J. Cole, Meek Mill, Pusha T, A$AP Rocky, Big K.R.I.T., Wale, Pusha T and even Big Sean among them.

“I got love for you all, but I’m trying to murder you,” he rapped. “Trying to make sure your core fans never heard of you.”
