Sarah Jessica Parker has shared her own crazy ‘Sex and the City’ fan theory, in which Samantha, Charlotte and Miranda are just made up characters in Carrie’s head.

Speaking on the Nerdist podcast, the actress said that she often wondered if Carrie’s girl friends were real, or if they’d just been invented for her newspaper column.

“I used to wonder if Samantha, Charlotte and Miranda were real,” said Parker. “They’re such perfectly archetypal characters.”

Parker then went on to explain her theory in full: “So you're writing a column about sexual politics and observations of female/male, primarily, heterosexual relationships, so you’re picking one type," she said.

"You’re saying ‘this type is this and this,’ and then you complicate it more, like any good writer does. So, I'm not entirely sure they're actually real.

"I think they're invented types, and that she is among them because that's her way of infiltrating story, and affecting story, too. We don't know if any of that stuff that happened is real. She's just writing it.

"She just writes a column week to week, right? Then we illustrate it for the audience […] what we are seeing isn't necessarily what happened in New York City, to real people that they were bumping into."
