Barry Levinson directed Ellen Barkin in her breakout role, 'Diner,' nearly thirty years ago, but for the past couple of years she's had a drastically different connection with the famed filmmaker: she's dating his young son.

Well, according to Page Six that is, whose multiple sources say the 57-year-old Emmy winner and writer Sam Levinson, 26, are not only an item but have actually been living together for two years.

"They go out, they're photographed together, they don't keep it secret," said one source (indeed, we easily found the photo at right of them, shot in January). Another calls the May-December romance "the worst-kept secret in New York."

Barkin's rep said the star does not comment on her personal life.

Her lush film career started in 1982's 'Diner.' Sam Levinson was three years from even existing when his famous dad directed the actress in the Baltimore-based nostalgia-fest. She's had other major roles in 'The Big Easy,' 'Fear and Loathing in Las Vegas' and 'Ocean's Thirteen,' among others.
