There’s nothing like a celebrity feud to take your mind off the important things in life. Whether it’s a fresh beef between stars you barely know or a long-simmering dispute between established names, a celebrity feud is the perfect distraction for tumultuous times. And these are tumultuous times.

Reality stars can feud with actors, athletes can feud with musicians, gossip columnists can feud with rockstars, and so on and so forth until Hollywood implodes.
