Cameron Diaz and Nicole Richie became sisters-in-law when they married twins Benji and Joel Madden, respectively, and the famous relatives certainly enjoy each other’s company. Diaz and Richie were spotted bonding in Beverly Hills, Calif., on Wednesday looking fresh-faced on a fun outing. The author of The Longevity Book, Diaz, showed off her ageless complexion, pulling her blonde hair back into a ponytail. Her daytime look consisted of a white tee, long denim skirt, brown patterned jacket, and nude slides. Her sister-in-law Richie went casual in a red and blue plaid flannel shirt, leggings, and Nike sneaks. She accessorized with aviator shades and threw her hair up into a topknot. This isn’t the only time we’ve seen these famous relatives bonding. Back in June, Diaz supported Richie at the launch of her new collection with Revolve, cozying up in this adorable photo.
