I tried heroin: Robbie Williams

London: Singer Robbie Williams has admitted he once took heroin and will always be tempted to take drugs.

The 38-year-old, who has had several stints in rehab to combat drug and alcohol addiction, admits there is a part of him that is "mad for" dangerous narcotics.

"Everything I like is addictive, destructive, or corrosive. Addiction to danger is no stranger to me, its fashion," contactmusic.com quoted Williams as saying.

"There`s always going to be a part of me that wants to exist in a psychedelic realm. I only did heroin once and never got addicted but there is still a lot of me that is mad for all that," he added.
