Macaulay Culkin made a rare public appearance at Comic Con in New York City on Friday, Oct. 11.

Culkin joined Seth Green, Breckin Meyer and Matthew Senreich at the Javitz Center event for their panel on Robot Chicken. Since 2005, Culkin has lent his voice to a number of characters on their cartoon on Adult Swim, including Bastian Bux and Billy.

At Comic Con, the often-reclusive former child star donned a pair of black jeans and a dip-dyed blazer over a white tank top. His blond hair fell to his shoulders and he was rocking a full goatee. Culkin accessorized with several bracelets and rings, black sunglasses – and furry bunny ears that matched ones worn by Green.

Over the last few years, reports have speculated that the Home Alone and Richie Rich actor may have been struggling from a drug problem due to his noticeably gaunt appearance. At the time, Culkin’s publicist vehemently refuted the rumors.

“The report in the National Enquirer that Macaulay Culkin is addicted to Heroin and assorted hallucinogenics is not only categorically without merit, but it is also impossibly and ridiculously fictitious,” the rep told E! News. "We beseech the responsible media to consider the source and its reputation and to please not perpetuate this destructive and insulting story by pursuing it any further."

Since the days of his childhood stardom, Culkin has kept a low profile, very infrequently appearing in live action projects. He was in Saved! with Mandy Moore in 2004 and acted in his last feature film, Sex and Breakfast, in 2007. At the Comic Con panel, a Culkin fan asked what he’s been doing, to which he replied, “Hiding under a rock somewhere.”

Green, a longtime pal of Culkin, then chimed in, adding, "The best thing about Mac is that he had a better career by the time he was 14 than most of us have in our whole lives. If he spends four years, six years, not doing anything, he'll still be more relevant than anyone here."
