Not only has Kesha toned down her "look" over the past few years, but she has also significantly changed the way she lives.

In a new interview, the 'Tik Tok' singer, 28, opens up about her battle with an eating disorder — and reveals she deprived herself of food as a coping mechanism to handling her overnight fame.

"I started to think being hungry to the point of feeling almost faint was a positive thing," she told Vogue. "The worse it got, the more positive feedback I was getting. Inside I was really unhappy, but outside, people were like ' Wow, you look great.'"

With that also came changing her mentality. The blonde beauty claims, "Part of being healthy is being positive. I don't pay attention to the Internet or bloggers."
