Beyonce Knowles has achieved all that she wants to in her career - but has found herself unable to step away from work as a result.

The Crazy In Love hitmaker found fame as the teenage lead singer of R+B group Destiny's Child in the late 1990s before pursuing a successful solo career.

But now the star wants to take a step back from her whirlwind working life - because she has found herself unable to "chill out".

She tells Elle magazine, "Being this huge pop star is not my focus right now. I've done that.

"I wanted to sell a million records, and I sold a million records. I wanted to go platinum, I went platinum. I've been working nonstop since I was 15. I don't even know how to chill out."
