Denise Richards can't deny it--she has a thing for bad boys. After rumors swirled earlier this week that she was quietly dating her longtime neighbor, Motley Crue bassist Nikki Sixx, the 'Starship Troopers' actress confirmed the relationship Thursday night, RadarOnline.com reports.

The actress was questioned about the rumored coupling on Bravo's show 'Watch What Happens Live.' "What is considered dating?" Richards said before confessing, "We have been out on a few dates, yes."

Richards went on to say that it's very early and they're keeping it casual. "You want if anything's gonna develop, you want it to develop on its own," Richards said. "That's the god's honest truth, we're taking it very slowly."

Many of Richards' previous relationships were with so-called bad boys, including a tumultuous marriage to Charlie Sheen and a year-long courtship with Bon Jovi rocker Richie Sambora.
