8 Legendary Duos Who Hated Each Other's Guts

4. Simon & Garfunkel

Nobody wants to be the Art Garfunkel in a relationship. Not even Art Garfunkel. But would you believe that the biggest rift to develop between on the biggest duos in music history stemmed from the jealousy... felt by Paul Simon.

It was Paul Simon who chose to walk away from their partnership, and the seed of his departure was first planted when both he and Garfunkel were given roles in the film adaptation of Joseph Heller's Catch-22. And then they cut Simon out of the movie. So while Art was off filming his part (for a much larger chunk of time than originally planned), Paul was back at home, growing increasingly furious with his other half for unintentionally delaying their final album, Bridge Over Troubled Water.

Up until this point, though, it was Art who was constantly feeling overshadowed by Paul. (Apparently George Harrison could see this, too, and noted to Art that "my Paul is to me what your Paul is to you." Translation: You're being sidelined.) So there was jealousy flowing freely from both sides. But Art would have stuck it out even though he was feeling more than a little under-appreciated in his role. In fact, 45 years later and Garfunkel is still reeling from it:

How can you walk away from this lucky place on top of the world, Paul? What's going on with you, you idiot? How could you let that go, jerk?
