Macaulay Culkin's Estranged Father Speaks Out Amid Heroin Addiction Allegations

Photos of a much healthier-looking Macaulay Culkin walking around New York City on Saturday haven't seemed to help dispel the National Enquirer's claims that the former child star is addicted to heroin.

The 31-year-old's rep vehemently denied the allegations, calling them "ridiculously fictitious," and the Enquirer shot back, defending its claims while urging the actor to seek help. Now, Culkin's estranged father, Kit, is speaking out and is concerned for his son's life.

"I hope that he has the right people looking after him," Culkin's father told the U.K. paper The Sun.

Kit has been estranged from his son for the past 15 years, but photos dating back to February that show a gaunt-looking Macaulay have him worried.

"Oh, gosh. Kit has seen the photo. But he can’t talk about it. He just can’t, because it hurts him too much. Of course he’s worried, he’s incredibly concerned," Culkin's stepmother Jeanette Krylowski told the paper, adding that when she saw the photos she thought, "'Oh no, this is not good. Either he’s dying of some disease or he’s heavily into drugs.’”

In March, a source told In Touch that Kit was "totally devastated" by the photos, and added that he had not seen his son since 1997, when Macaulay fired him as his manager, due to his parents' fighting over control of the former child actor's personal fortune.

Though there have been reports that Macaulay allegedly turned to drugs after he split with Mila Kunis, his girlfriend of eight years, in 2010, his stepmother believes that it was the death of his sister Dakota, who died in a car crash in 2008, that caused the actor's life to allegedly unravel.
