Is Cameron Diaz dating again?

The 41-year-old actress has been spotted several times over the last month with Good Charlotte rocker Benji Madden; including at the release party for Vicky Vlachonis’ new pain-relief book “The Body Doesn’t Lie” in Los Angeles last week, according to Us Weekly.

The alleged couple was also spotted leaving the Los Angeles Equinox gym on Friday.

A source told People that “they seemed very friendly and they looked like they were trying to avoid (being seen outside), but Cameron was super friend with other people (at the gym.)"

Another source said they have spent a lot of time together at the actress’ house and they seem like they are dating.

“He is the nicest guy and treats her like a lady,” the source continued.

Madden, 35, and Diaz could have met through her gal pal Nicole Richie, who is married to the rocker’s brother, Joel Madden.

Reps for both stars have declined to comment on the rumored relationship.

The rocker would be the first high-profile relationship Diaz has had since her highly publicized relationship with New York Yankees slugger Alex Rodriguez, which ended in Sept. 2011. Her other exes include Justin Timberlake and 30 Seconds to Mars rocker Jared Leto.

Madden was previously linked to socialite Paris Hilton.

A source told Us Weekly that the relationship is “very new” and that they are just “hanging out.”
