"The mutual decision was reached amicably and they remain committed to raising their two young children together," Slater's publicist, Evelyn Karamanos, said in a statement Wednesday. "They ask for the respect of their privacy at this time."
Slater's films include "Windtalkers," "Hard Rain," "Broken Arrow" and "Interview With the Vampire."
The brief marriage had seen its share of turmoil.
In November 2003, Haddon allegedly hit Slater with a drinking glass in a room at a hotel-casino in Las Vegas.
Slater required stitches to close a wound behind the ear, police said.
Haddon was jailed briefly but no charges were filed.
