Cameron Diaz and Nicole Richie hit the hiking trails with their dogs in LA on Sunday. This isn't the first time we've seen the two working on their fitness together; they were spotted hiking together in February as well. The two seem to run in the same Hollywood circle, with Gwyneth Paltrow as a notable mutual friend. Nicole and Gwyneth met up for a star-studded dinner just last week, and Gwyneth and Cameron are longtime friends.
Cameron's finally back in LA after a promotional tour for The Other Woman with her costars Leslie Mann and Kate Upton. The trio shared plenty of golden moments during their press rounds, including Leslie grabbing Cameron's butt and plenty of raucous fun at the MTV Movie Awards. The film hits theaters this Friday.
