Denise Richards and Nikki SixxActress Denise Richards has reportedly split from rocker Nikki Sixx after just a few weeks of dating.

After reports that the pair had split up surfaced Saturday, Us Weekly says a source in Richards' camp confirmed the reports but also said that the couple were never that serious to begin with.

"It's crazy how this is being made out to be some big breakup," says the source. "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."
