Pop star Kesha has opened up about her "miserable" life before she checked into rehab to tackle an eating disorder.

The TiK ToK hitmaker took time out from the spotlight last year (13) to seek professional help for her personal issues.

She has now spoken in detail about her state of mind before her 60-day stint in the Timberline Knolls clinic in Illinois, revealing that recording her second album Warrior left her in a dark place.

She tells Teen Vogue magazine, "Let's just get the elephant out of the room. My eating disorder is something I've been struggling with for a while. People will make up stories, but I went to rehab for an eating disorder - nothing more and nothing less.

"Making my last record, Warrior, was a pretty miserable process, and it wore my spirit down. I was fighting like hell to keep my whole irreverent essence and everything raw and visceral that I stand for in it, but in the end I was promoting something that wasn't the animal I wanted it to be. I decided to face my problem head-on."
