“KEVIN!” Catherine O’Hara and Macaulay Culkin haven’t shared the screen since “Home Alone 2: Lost in New York” in 1992, but fans of the movie franchise are still curious about their relationship. While on Bravo's “Watch What Happens Live” with Andy Cohen, O’Hara revealed that she actually had a short reunion with her on-screen son about a year and a half ago.

When a fan called in and asked O’Hara, 60, if she has kept in touch with Culkin, 34, the actress explained that she ran into him at a Martin Mull art opening.

“He was coming out and he went, ‘Mommy,’ ” O’Hara told the audience, opening her arms. “And I said, ‘baby.' ”

The actress said her husband snapped a photo of the pair. “He was living in Paris at the time and he looked lovely and he was doing really well,” she added of Culkin. “I was happy to see him. ... Love him.”

Macaulay Culkin has kept a low profile recently but is no stranger to making headlines. In 2012 the actor was photographed looking gaunt, fueling speculation of a drug problem. By 2013 he appeared to be on a better path, looking healthy and interacting with fans at Comedy Central’s “Robot Chicken" panel at New York Comic Con. In November he had fun with a death hoax that was circulating. His band, the Pizza Underground, posted photos of them reenacting scenes from the 1989 comedy about a corpse, “Weekend at Bernie’s,” with the former child actor.
