Two music icons have finally buried the hatchet. Footage surfaced on Wednesday (May 27) showing pop singer Katy Perry, 41, and Chicago rapper Chief Keef, 30, reuniting in a rehearsal studio, sparking speculation about a potential collaboration. Their long-standing feud dates back to May 2013, when Perry tweeted that hearing Keef’s “Hate Being Sober” on the radio gave her “serious doubt for the world.” Chief Keef fired back with hostile tweets and a threat at the time, but twelve years later, it looks like it’s all love between the two.
