Is Nikki Sixx Dating Denise Richards?

New couple alert? Denise Richards loves the bad boys!

The former Bond Girl is reportedly bumping uglies with Motley Crue bassist Nikki Sixx. According to a source close to the actress, Richards and Sixx have been neighbors “for years” but only recently began dating.

Sixx called it quits with longtime flame Kat Von D last summer.

“They have a lot in common and are taking things slowly,” the insider claims.

Neither Richards, 39, nor Sixx, 52, have commented.

Denise Tweeted a birthday message to Nikki earlier this month, but that’s as public as the alleged romance has gone. Though neither are strangers to the Hollywood scene. Richards was previously married to Two and a Half Men star Charlie Sheen. They have two daughters. Sixx, on the other hand, has been married to a pair of Playboy Playmates — Brandi Brandt and Donna D’Ericco. He has three children with Brandt and one with D’Errico.
