According to reports, the Holiday actress and guitarist Benji have been quietly seeing each for around a month.
A source told America's People magazine: "Cameron seems very happy with Benji. He is the nicest guy and treats her like a lady."
It's been claimed that Cameron, 41, and Benji, 35, were introduced via Nicole Richie, who is married to Benji's twin brother Joel Madden, with a source telling Us Weekly that Nicole "thought they would click."
So far, neither Cameron or Benji has confirmed the romance.
Just last month, Cameron said she wasn't actively looking for love, telling Us of boyfriends: "I don't think you find them, I think they find you. My feeling about it is you should just be open to receiving."
Cameron's previous boyfriends include Justin Timberlake and Jared Leto, while Benji has dated Paris Hilton, Holly Madison and Australian star Sophie Monk.
