Taking the lead on our most unexpected couples list are Cameron Diaz and Benji Madden, who are now an item, a source shared with Us Weekly.

“It’s very new,” said the source. Apparently the actress and Good Charlotte singer are “just hanging out” and have only been dating for the past several weeks.

It’s hard to imagine that the two stars run in the same circles, but a mutual friend was all they needed to spark the romance. The pair were introduced by Benji’s sister-in-law Nicole Richie, wife to brother Joel Madden. “Nicole thought they’d click,” the source revealed.

Cameron and Nicole have recently been spotted hanging out on multiple occasions, creating plenty of opportunity for Nicole to talk up the single Madden twin. The matchmaker must be pretty savvy at connecting couples, or maybe she just really wanted to help Cameron get back on the relationship wagon. The 41-year-old actress hasn’t been paired with anyone publicly since her 2011 split from New York Yankees third baseman Alex Rodriguez.

Best of luck to the new couple!
