Last year, there were allegations that Macaulay Culkin was struggling with a heroin and prescription drug addiction. Although his rep denied rumors that he was having health issues, many were concerned after he was spotted looking frail and unhealthy. Apparently his ex-girlfriend of eight years, Mila Kunis, even tried to get him to seek help.

But now, a year later, the 33-year-old Home Alone actor is looking like a whole new person. Seen at the Adult Swim and Oldboy New York Comic-Con panels at the Javits Center in New York City on October 11, Macaulay, Seth Green, Jason David Frank, and more actors signed autographs and spoke on the panel.

Macaulay looked healthy and seemed to have put on weight since last year. Along with his beard and long hair, the child star also got playful on the panel while wearing pink and white animal ears.

We're happy to see Macaulay looking much healthier. What do you think about his rugged look? Weigh in below.
