Alyssa Milano and Shannen Doherty
This one goes down as one of the greatest costar feuds of all time. Alyssa Milano and Shannen Doherty co-starred in the original version of ‘Charmed’ back in the late ’90s and early ’00s. Things were apparently so bad on set that Doherty left the show after season three.

Milano said in 2013 during an interview on Watch What Happens Live: “ I don’t know if she got fired, we never really found out what happened. I can tell you that we were on the air with her for three years and there were definitely some rough days .”
In a 2001 interview with Entertainment Weekly, Milano said, “I think it’s hard when you put… two very different people together. I’m very laid-back and passive. I have my Buddha. I come in here and meditate. [Shannen’s] got a lot of energy, she’s very headstrong, she wants to get the job done.”
