It looks as if Macaulay Culkin has been left home alone — without any food.

The former child star looks nothing like the adorable 8-year-old he once was in the movies, appearing gaunt, pale and skeletal as he posed for pictures with fans in the city this week.

The shocking pictures have fans of the “Home Alone” star, now 31, worried he might be seriously ill.

But a rep for the manorexic-looking movie star claimed yesterday he’s in fine shape and has no problem with drugs or alcohol.

“Macaulay Culkin is in perfectly good health,” his rep, Michelle Bega, said. “For any media outlet to speculate otherwise is reckless, thoughtless and destructive.”

Culkin was busted for possessing pot, Xanax and pain pills in 2004.

Bega refused to say how Culkin supports himself, but admitted he has no upcoming projects.

Industry sources said Culkin pays bills with millions he still has left from his years as the world’s most successful child star since Shirley Temple.
