The 27-year-old 'Die Young' hitmaker, who has joined the singing competition 'Rising Star' after her two months rehab stint, said she realised that she was being hateful to herself and was really hurting her body by meeting the unrealistic expectations of the music industry for what a body was supposed to look like, reported Us magazine.
"I take my music and career very seriously, and certainly didn't land in this situation from partying. But I was cut off from the outside world and I imagined people making up stories at a time when what I really needed was support.
The star, now dating Brad Ashenfelter, also explained how she knew she was ready to leave rehab behind.
"I knew I was ready to leave when I'd gained enough confidence to get on a plane knowing there would be paparazzi at the airport at the other end. I was right - they were there. But this time, when I saw the pictures, I felt OK," she added.
