Speaking to Howard Stern on SiriusXM, she added: "Hey, listen, I just don't like being set up. I don't like it. I hate it."
Last year, sources said the Friends alum wasn't "concerned about dating" following her split from Theroux, whom she split with in 2017, two years after marrying in 2015.
The insider said: "She isn't concerned about dating. She is happy to focus on work.
"She doesn't even talk about [Justin] anymore. She doesn't keep up with what he does. She is focusing on her own life."
Meanwhile, Aniston - who was also married to Brad Pitt from 2000 to 2005 - previously revealed she is "not heartbroken" over her separation from the 48-year-old actor.
She said: "The misconceptions are 'Jen can't keep a man,' and 'Jen refuses to have a baby because she's selfish and committed to her career.' Or that I'm sad and heartbroken. First, with all due respect, I'm not heartbroken.
"And second, those are reckless assumptions. No one knows what's going on behind closed doors. No one considers how sensitive that might be for my partner and me. They don't know what I've been through medically or emotionally."
