Is Cameron Diaz dating Benji Madden?

THEY’VE been spotted working out and partying together, so are these two stars just good friends or is it the beginning of a serious relationship?

CAMERON Diaz might have snagged herself a new man.

According to People, the 41-year-old actor is reportedly dating Good Charlotte’s Benji Madden. The Other Woman star and the 35-year-old rocker have allegedly been spending quality time together over the last month and were pictured leaving a Los Angeles Equinox on Friday, May 16, after hitting the book launch of The Body Doesn’t Lie the night before.

Cameron Diaz recently starred in The Other Woman with Leslie Mann, Nicki Menaj and Kate Upton.

“They seemed very friendly,” a source told People of their gym outing.

“And they looked like they were trying to avoid [being seen outside], but Cameron was super friendly with other people [at the gym]. She even taught a girl how to use one of the arm weight machines.”

Us Weekly reports that the relationship is “very new” and that Diaz and Madden are “just hanging out.”

Benji‘s twin brother Joel Madden is a judge on The Voice.

Reps for both stars were not immediately available for comment.

Diaz is friends with Nicole Richie, who is married to Benji’s twin brother, Joel Madden. The pair has two kids together, Harlow, 6, and Sparrow, 4.
