US Weekly reports that Richards, 39, is dating Motley Crue bassist Nikki Sixx. An unnamed source tells the magazine that she and the 56-year-old rocker "have been neighbors for years. They have a lot in common and are taking things slowly."
Richards and Sixx were allegedly spotted having breakfast together on Dec. 12. "Nikki was telling stories, and Denise was laughing," a witness claims.
But, things might not be so easy for the possible pair. In addition to Richards' complicated life with Sheen (with whom she has two children), Sixx has a not-so-simple love life of his own.
Married twice before, the rocker also had a two-year relationship with L.A. Ink star Kat Von D (who's now linked to fellow bad boys club member Jesse James). Back in October the the former couple was spotted "acting pretty cozy and chummy" with one another, raising suspicions that Von D, 28, and Sixx might not be done for good.
Still, Sixx seems undeterred and even hinted around about his latest relationship on the web. He posted from his Twitter page on the eve of his birthday, that he had "a midnight rendezvous planned with a beautiful maiden."
He even indulged in some Twitter TMI when he later wrote, "Perfect end to a perfect weekend...Thanks for all the b-day spankings..:)"
