(Cover) - EN Showbiz - Lenny Kravitz thinks the next 20 years of his career will be the most interesting.

The 47-year-old rock star has been making hit music since the 80s.

He is currently promoting Black and White America, which is his ninth studio album and scheduled for release at the end of August.

Lenny is proud of the work, and has no plans to slow down.

"Not at all!" he exclaimed when asked if he will soon retire. "I'll just keep going man. The first 20 years were the start. The next 20 will be really interesting."

When he isn't making music, Lenny keeps himself occupied with his own interior design company.

It has been doing particularly well recently, and Lenny is excited about working with some of the design world's biggest names.

"I have a company called Kravitz Design and actually we've been blowing up [recently]," he enthused.

"I'm doing a lot of work right now... I'm doing a project with Philippe Starck at his new hotel in Miami." (C) Cover Media
