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. 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$AP Rocky’s “(Expletive) ’ Problems" that same year. In 2013, Pulitzer Prize winner Lamar was featured on Big Sean's “Control,” in which he called out a slew of contemporary rappers including Drake, J. Cole, Meek Mill, Pusha T, A$AP Rocky, Big K.R.I.T., Wale, Pusha T and even Big Sean among them.
