Cameron Diaz and Benji Madden are getting serious

“I’m really happy right now,” the 35-year-old musician said to People about his romance with Cameron Diaz, 41. Sources close to People also said that the new couple was already talking about getting married.

Another source told the entertainment magazine that Benji is already practically living at Cameron’s house, and they just got back from spending some quality time on a yacht touring the French and Italian coasts. When they’re at home they hang out a lot with Benji’s brother Joel and his wife Nicole Richie.

Benji also revealed that the Sex Tape star “inspires” him. “It’s same for any man, no matter what they do. It drives you,” he said. “All people, I think, react the same way to the same situations, like we were saying with Joel being a father, we all want to be the best we can be.”

Benji has previously dated Paris Hilton, Holly Madison, and Eliza Doolittle, but it looks like he’s getting serious with Cameron. They’ve only been dating since May, but Benji has already met Cameron’s family during a 4th of July bash.
