Berry has since stepped out with sexy French actor and Dark Tides costar Olivier Martinez -- but has said she and Aubry remain close.

"You realize you are not meant to go the distance with everybody," she told Vogue of their split. "We were meant to bring this amazing little person into the world. And I think that's why we came together. And because of that, we are going to be together forever, all three of us."
