The Glee star, 23, told PEOPLE on Friday that he makes "a great deal of effort" to stay out of the controversy that some of his castmates have unfortunately been unable to avoid.
"It's really sad," he said. "I've seen some of my closest friends on Glee go through where these horrible things are written about them and none of it is true, but some reporter wants to get a hit, they say so-and-so is a raging bitch."
Most recently, Colfer's allegedly fired costar Naya Rivera has been in the news for apparent bad behavior on set – a matter the actor said he'd "rather not" discuss.
But when it comes to his own life, "I just mind my own business, really," he said. "I don't want to say life is too short for drama, but I think I'm just too old for drama. I'd rather go home and be with my cat and my dog than start a war with someone."
As far as on-set tension goes in general, the upcoming Hot in Cleveland guest star said, "It's really unfortunate. There's almost no point in ever clearing anything because people are just going to write what they want."
"People have written fake stories about me dying before because they know it's a guarantee hit on their link," he said. "No matter what I say, people are going to take it and spin it. Everyone clicks on that link as opposed to, 'Ooh, check out Chris Colfer's children's series.' No one wants to click on that."
