Lenny Kravitz has credited his actress daughter Zoe with helping him sober up after a lengthy period of heavy drug use.
 
The rocker admits he spent quite some time partying and staying high all the time at the height of his success, and then his 11-year-old daughter came to stay with him and he had to clean up his act.
 
The "Let Love Rule" singer tells Men's Journal magazine, "I had to surround myself with energy and chaos and excitement and conflict. For a bit I was high all the time, just medicating... I suppose that was so I didn't have to feel certain things."
 
But when his daughter came to live with him full-time, Kravitz knew he'd have to change his ways: "It was the best thing that happened. I had to change my life. I was in the middle of my craziness. I had to focus, and I wanted to focus, but all of a sudden, here it was. I began to slowly change my life.
 
"If that hadn't happened, I don't know where I'd be now."
