Nicole Richie: Cameron Diaz & Benji Madden's Matchmaker

It helps to have Nicole Richie as a sister-in-law!

When it comes to Cameron Diaz and Benji Madden’s budding relationship, they have Nicole – who is married to Benji’s twin brother Joel – to thank.

On Tuesday’s “Watch What Happens Live,” Andy Cohen asked Nicole about the couple’s new relationship.

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

So was Nicole the couple’s cupid?

“Yes,” she told Andy. “I’m going to take responsibility for everything!”

Speaking of love, how is Nicole’s love for one-time BFFs Paris Hilton and Lindsay Lohan?

“Paris is somebody that’s been in my life since day one. I haven’t spoken to her in a while technically, but if you really want to get into it, my view of a friendship is somebody that you don’t necessarily have to talk to every day, somebody that you can call when you need them and they’re just going to be there. Time of whether I’ve spoken to somebody is really…it doesn’t really matter, in my opinion. An idea of a true friend is somebody that’s going to be there with you through and through,” she said of Paris.

Adding, “The short answer is I haven’t spoken to her in a while, but we are very good friends and I love her and love her family and have a lot of respect for her.”

And what about Lindsay?

“Haven’t spoken to her in a while,” she curtly said with a deadpanned expression.
