Rumors are surfacing that former child star Macaulay Culkin is addicted to heroin!

Culkin has reportedly been seen shooting up heroin and using the highly addictive prescription painkiller oxycodone.

Eye witnesses say the 31-year-old actor shoots up heroin on a regular basis and that he had nearly overdosed one time!

Although Culkin’s legal team denies any overdose or purchase of prescription drugs, it is being reported that the Home Alone actor spends up to $6,000 a month on power painkillers.

A source reveals that the actor’s drug use intensified over a year ago and was sparked by his break up with Mila Kunis, who is now reportedly dating Ashton Kutcher.

“He’s been hooked for a year and a half, and his drug of choice is either heroin or oxycodone. Mac is surrounding himself with junkies and lowlifes. It’s a real tragedy,” says an insider.

“Macaulay Culkin is surely dying. He’s addicted to heroin, oxycodone, Percocet and Vicodin,” says another source. “I have witnessed his drug taking, which has escalated over the past year and a half to the point where he needs serious help.”

“His closest friends fear that he’ll overdose or his heart will explode. If he doesn’t get help and enter rehab now, he could be dead in six months.”

Let’s just hope he gets treatment before something tragic happens.

Good luck Macaulay.
