Looking for your one true love?

If Nicole Richie is in your social circle, she’s your girl — as in, she’ll set you up.

On Tuesday’s Watch What Happens Live, Richie happy answered Andy Cohen when he asked if she was responsible for the blossoming romance between Benji Madden (her brother-in-law) and the beautiful Cameron Diaz.

“Yes. I’m going to take responsibility for everything,” she said with a grin, as fellow guest Rachel Maddow looked on.

Moments before, Richie also answered a fan who asked if she approves of the relationship.

“I approve of anything that’s going to make Benj happy and I am a devoted sister-in-law . . . I am happy for anybody who’s happy and I want everybody to be surrounded with love, whatever that means,” according to Richie.

Word of Diaz and Madden’s romance first spread some two months ago, when the pair attended a book launch party and went to the gym together in the same week.

In June Madden kinda sorta confirmed he was dating his sister-in-law’s close friend. And just last weekend, Diaz and Madden were spotted in Florida spending Fourth of July together.
