Denise Richards and Nikki Sixx: It's Already Over!

Brace yourself, THG readers. An iconic Hollywood couple has broken up.

Following a month of dating, Denise Richards and Nikki Sixx have called it a relationship, with a source close to Charlie Sheen's ex saying the fling was never serious.

"They were never exclusive or serious to begin with!" says an insider. "I could count on my hand how many times they went out. They decided to try it and she was not intereste. That's dating! This isn't some big, dramatic split."

Hey, speak for yourself, anonymous source. We thought these two would be the next Brangelina.
