"Lost" actors Maggie Grace and Ian Somerhalder, who played step-siblings Boone and Shannon, are rumored to be dating in real life.

The couple is regularly spotted out together in Los Angeles, but have tried to keep their budding relationship a secret.

A source confirmed the romance by saying, "They stay out of the limelight, but they spend a lot of time hanging out and working out together at Gold's Gym [in Venice Beach].

"They kiss and hold hands when they come and go from the gym. You can tell they're a couple."
