Denise Richards has a new boyfriend. The actress - who has daughters Sam, six, and Lola, five, with ex-husband Charlie Sheen - is reportedly dating Motley Crue bassist Nikki Sixx and friends have revealed the pair are taking their relationship slow. A source told US Weekly magazine Denise and Nikki "have been neighbours for years. They have a lot in common and are taking things slowly". The pair were spotted on a breakfast date in California on Sunday (12.12.10) where witnesses said Nikki, 52, and Denise, 39, looked extremely happy together. The source said: "Nikki was telling stories, and Denise was laughing." Last Saturday night (11.12.10) the rocker tweeted he had "a midnight rendezvous planned with a beautiful maiden." Denise has previously revealed she finds it difficult to combine the needs of her children while having a personal life. She said: "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!" Former heroin addict Nikki - real name Frank Carlton Serafino Ferrana, Jr. - has been married twice before to Playboy Playmates Brandi Brandt and Donna D`Errico.
