Los Angeles: Actress Denise Richards has reportedly parted ways with rocker Nikki Sixx.

Richards, 39, began dating the 52-year-old Motley Crue bassist in December. According to insiders, the romance was never that serious.

"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," a website quoted an insider as saying.

"They decided to try it and she was not interested. That`s dating! This isn`t some big, dramatic split," the insider added.
