Denise Richards and Nikki Sixx split

According to Us magazine, the couple has taken different paths.

“They have a lot in common and are taking things slowly,” a source said in December.

However, another source said today that their romance was nothing serious and it’s not really a separation since their story never began.

“It’s crazy how this is being made out to be some big breakup. They were never exclusive or serious to begin with! I could count on my hand how many times they went out. They decided to try it and she was not interested. That’s dating! This isn’t some big, dramatic split,” the source continues.

The actress’ rep didn’t comment on the news of the separation.
