Cameron Diaz Congratulates Nicole Richie on Her Clothing Line With a Sweet Instagram Post

Cameron Diaz and Benji Madden made a rare outing together on Thursday night when they attended the launch party for Nicole Richie's House of Harlow x Revolve clothing line in LA. The couple, who have been married since January 2015, looked so happy as they posed for the cameras and cozied up to each other at the outdoor event. In addition to their sweet moments, Cameron also posed with her sister-in-law Nicole in front of the picturesque sunset and mingled with her brother-in-law (and Benji's twin brother) Joel, and Nicole shared a laugh with her dad, Lionel Richie.

On Tuesday, the actress took to Instagram to congratulate Nicole, writing, "We're sisters because of our misters and I am SO impressed by and proud of how talented she is. Her capsule collection at Revolve is a wonderful reflection of her spirit and her style; sexy and chic, playful and grounded, feminine with a hint of masculine, retro yet contemporary. Congrats and 😘😘😘 @nicolerichie #hohxrevolve." Keep reading to see more from the fun night, then find out Cameron's cute nickname for Benji.
