Cameron Diaz, Gwyneth Paltrow & Chris Martin -- The Three-Way Dinner Date

It was a mnage trois dinner date, as Cameron Diaz got cozy with new bestie Gwyneth Paltrow and her Coldplay hubby Chris Martin while enjoying some sushi at Sugarfish in Brentwood on Monday.

Just a bunch of average, everyday super famous A-list beautiful people grabbing a casual bite to eat together. No biggie.
