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.
