Model-turned-actress Amber Valetta was addicted to drugs and alcohol at the height of her catwalk fame.

The Revenge actress, 40, told a live seminar for wellness website last week (ends13Jul14) that she began trying to get high from glue and scented pens when she was only eight years old.

Her habit took a turn for the worse when she moved to Europe at the age of 18 to pursue her modelling career, and cocaine and alcohol became readily available.

The catwalk beauty, who fronted campaigns for Versace and Calvin Klein, says, "I was at the top of my game, probably 20 years old, had everything in front of me and I put everything on the line for my addiction. Everything. All my friendships, my family, my job. I had a multi-million dollar deal and I showed up the first day to shoot this campaign high and drunk. I didn't care. And that's just to show you that addiction takes you to the worst places...

"I'm not a victim, I do not blame my parents, I don't blame my family, and I don't blame anything that happened to me that was negative. I think it does affect me and I'm sure it made me partially who I am and want to get out of myself, but I know for certain that I am an addict through and through. Even if I'd had this blessed and amazing childhood I'd still want to get higher, I'd still want to get out of myself."

Valetta got sober at 25 but insists it is still a challenge to stay clean, adding, "My disease is only an arm's length away from me... I got sober and how I stay sober today 15 years later is that I continually turn inward and look at my disease because my disease shapeshifts."
