‘I did a 90-minute workout at 2am!’: Lenny Kravitz on

The musician has embraced clean living, even if it sometimes means wearing leather trousers to the gym. He discusses celibacy, discipline, his new music – and why he hasn’t been in a serious relationship for nine years

Nobody does rock star like Lenny Kravitz. He pads into the recording studio like a tranquillised tiger. It’s dark in here, but he is wearing shades. He’s got on a leather jacket, skinny black jeans, a T-shirt made from metallic shards. His dreadlocks reach way down his back and are as black as his designer stubble. Kravitz, who has spent much of his adult life topless, has a 28in waist and an eight-pack that could double as a xylophone. Last Sunday, he celebrated his 60th birthday and he’s every bit as gorgeous as he was when he made his name in the late 80s; possibly more so. The consensus seems to be that he’s the hottest 60-year-old man on the planet.

I can’t believe you’re 60, I say. “I can barely believe it myself. But it’s beautiful,” he says. Is it in the genes? “It’s a combination of genes, self-care, hard work and discipline.”
