Nicole Richie Responsible for Benji Madden-Cameron Diaz Hookup

Are you loving the unlikely pairing of tattooed rocker Benji Madden and Hollywood actress Cameron Diaz? Yep, Nicole Richie will totally take credit for that.

During an appearance on Bravo’s Watch What Happens Live Wednesday, the Candidly Nicole star (who is married to Benji’s twin brother and Good Charlotte bandmate Joel) revealed that she approves of the red-hot new romance because she was the one behind it.

“I approve of anything that’s going to make Benji happy. I am a devoted sister-in-law. I’m happy for anyone who is happy and I want everyone to be surrounded with love…Yes. I’m going to take responsibility for everything.”

Benji, 35, has reportedly been dating Sex Tape star Cameron, 41, for a few months. Both have been in high-profile relationships before (Cameron’s dated Justin Timberlake and Alex Rodriguez, while Benji’s been linked to Paris Hilton and Sophie Monk in recent years.) and have been careful to stay tight-lipped about their blossoming romance.
