Titanic stars Kate Winslet and Leonardo DiCaprio and director James Cameron last week donated tens of thousands of dollars to the last remaining survivor of the doomed ocean liner. The stars opened their wallets after learning that 98-year-old Millvina Dean, who was 9 weeks old when she was rescued from the Titanic, was having trouble paying her nursing home bills. The friend of Dean who contacted them said he was still waiting to hear from Celine Dion, who sang the movie’s centerpiece song.
