It's not too often Hip Hop artists settle their conflicts over Twitter. That particular online medium seems to be reserved for flaring public beefs rather than squashing them, which is why Wale and Kid Cudi's public peacemaking comes as a surprise.
The two crossed wires last September when Wale mentioned Cudi in a song. Cudi shot back in Complex Magazine by calling his DC-based peer "a simple-ass rapper." Both artists addressed the beef, but never attempted to make amends until now.
According to Rap Radar, Wale and Cudi also spoke on the phone to make peace.
