Jennifer Aniston has insisted that she doesn't hold a grudge over anything that has happened in her past, saying that harbouring resentment is like "taking rat poison and waiting for the rat to die". The actress was famously married to Brad Pitt when he fell for Angelina Jolie on the set of Mr And Mrs Smith in 2005 and made a veiled reference to their relationship in a new interview with Harper's Bazaar, saying that it's "extremely important to forgive". "Otherwise it just builds up like toxic waste. There's nothing worse than holding a grudge. Listen, people can do unforgivable things, but you have to let it go and say, 'Look, we're all human beings. We make mistakes.'" However, she admits that the constant claims by the media that she was miserable and bitter following the couple's split had gotten to her in the past and that finding a "detachment" had brought her to a happier place. "Seriously. How many times can I be out there in the world, enjoying my life, and yet the narrative is 'Poor, Sorry, Sad in Love Jen' … whatever the stupid headline is," she said. "There was a part of me that used to get very upset. I was guilty of getting too up in arms about stuff that wasn't real, phantom boxing with something that's not even there. Now I'd rather just focus on people and things that are here, happening, and what's yet to come. My friends, my family, wonderful people I work with. We know what the real is." The Horrible Bosses star also gushed about fiancé Justin Theroux, saying that he "is one of the most humble, decent human beings. He's not an ass.". "It's almost impossible to get bored with one another. We've tried so hard! And even that's interesting because his eyes are so pretty, but we can entertain ourselves and talk about endless things, which is pretty great."
