Martinez (whose exes also include Mira Sorvino and Rosie Huntington-Whiteley) and Dark Tides costar Berry, 45, went public with their romance in September 2010. The handsome actor was initially Berry's rebound from Gabriel Aubry, her love of five years (and father to her daughter Nahla, 3), with whom she split that spring.

For her part, Minogue is now dating Spanish model Andres Velencoso; proving they're still amicable, Martinez even took Berry to Minogue's sold-out May 2011 concert in Los Angeles.

Twice-divorced Berry "had given up on being married, but she trusts Olivier. He makes her feel safe. He's a keeper!"
