Denise Richards reportedly dating Nikki Sixx

39-year-old Charlie Sheen ex Denise Richards is reportedly dating Motley Crue bassist and recovering heroin addict Nikki Sixx, according to sources who know the pair and chose to not be identified.

Richards divorced Sheen back in 2006, amid allegations that the actor was addicted to drugs, sex and gambling. Reports that Richards is now dating 53-year-old Sixx indicate they are “taking it slow,” and cite a breakfast date in the Calabasas, California area in which Richards and Sixx are neighbors. The rumors seem to stem from a cryptic Twitter message from Sixx about a late night date followed by a sighting of the pair the following morning:

Sixx alluded to someone special on his Twitter.com blog on Friday night, revealing he had “a midnight rendezvous planned with a beautiful maiden”.

And Usmagazine.com reports the mysterious maiden is in fact Richards, after the pair was spotted getting cozy over breakfast at a Calabasas, California restaurant the following morning.

Richards has previously stated she is reluctant to introduce new beaux to her two daughters with Sheen:

“Dating is very challenging. I won’t introduce my kids to anyone I’m dating unless it’s very serious. And balancing everything – my daughters always come first. I will never get these years back with my girls!”

Richards was most recently linked with Richie Sambora, and Sixx dated celebrity tattoo artist Kat Von D.
