Nicole Richie set up Cameron Diaz and Benji Madden

Nicole Richie – professional matchmaker? The 32-year-old reality star admitted on “Watch What Happens Live” that she played Cupid setting up her brother-in-law Benji Madden with pal Cameron Diaz.

A viewer asked the 32-year-old reality star if she approved of Madden’s new girlfriend, to which she replied, “I approve of anything that’s going to make Benji happy,” she 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.”

Richie has been married to Madden’s twin brother, Joel Maddon since 2010. They have a daughter and son together, Harlow and Sparrow.

When show host Andy Cohen inquired whether she was the romantic go-between, Richie admitted, “Yes, I’m going to take responsibility for everything!”
