The 36-year-old, who recently filed papers to annul her whirlwind marriage to country singer Kenny Chesney, always feels devastated when her romances come to an end.
She admits, "I've had my heart broken. God, yes! I've had my bag-of-chips-on-the-couch-alone nights."
But the stunning actress believes her lowest point came when she discovered a former boyfriend had committed suicide in 1995.
She says, "It came at a time when I was at a crossroads in my life, and there was not a lot of light."
She insists, "Only someone in this business understands my weird life."
