"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," Culkin's rep told OnTheRedCarpet.com on August 2, 2012.
"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," his rep continued.
Culkin first sparked concern in February after photos were published of the actor looking thinner than usual. The actor's rep told OnTheRedCarpet.com at the time that his client is not ill.
The websites of the television show "Entertainment Tonight" and of the UK newspaper The Sun are among the outlets that published the photo, which is owned by the paparazzi agency INF and was taken in New York on February 8. The 31-year-old former child star, who has usually appeared trim, showcases defined cheekbones and sports a goatee.
Culkin has in recent years appeared on the television series "Kings" and voiced characters on the animated show "Robot Chicken" but is perhaps best known for his role as Kevin McAllister in the "Home Alone" comedy films. He played a child who battles two burglars in his home and in New York City after his family flies away on vacation without him by mistake.
He also appeared in movies such as "Uncle Buck," "My Girl" and "The Good Son" and in his friend Michael Jackson video for "Black and White," which was released in 1991.
