Cameron Diaz Goes on a Hike With a Friend in LA

Cameron Diaz went hiking with a friend in LA yesterday wearing an all-black outfit for the fitness excursion. The actress is no stranger to the buddy workout system. Cameron teamed up with close friends Drew Barrymore and Reese Witherspoon for a girls' getaway in Mexico earlier this month, which reportedly involved a bikini bootcamp program. The ladies showed off their hard work on the beach, adding to the long list of hot stars in our ultimate bikini slideshow.

Cameron may have wrapped up her fun in the sun, but she's still got a busy schedule ahead of her. Her film Gambit, which was released overseas last November, will hit theaters in the US this year. She also has The Counselor, with an all-star cast including Brad Pitt, Javier Bardem, and Penélope Cruz, coming to the box office this November.
