LOS ANGELES — One of John Travolta's co-stars says the actor is still "struggling" to cope with the loss of his son, six months after the teen's death.

Denzel Washington, who stars with Travolta in the upcoming remake of "The Taking of Pelham 1 2 3," spoke with Travolta earlier this month and says, "needless to say, he's struggling."

Washington says "more than talking to him," he "listened to him for about two or three hours."

He says "it's going to take time" and asks "what can you say? Just be there as a friend because he's such a sweet, sweet person."

The chronically ill Jett Travolta died in January after he suffered a seizure at a family vacation home in the Bahamas.
