Kelly Osbourne says nasty comments on her body before losing weight led her to abuse drugs.

“I understand that being judged by others comes with the territory, but it broke my heart and ruined my self esteem,” she said of the things people said about her.

“It sets you up to hate yourself in a huge way. I was so angry about the things people said about me. I truly believe it’s the main reason I turned to Vicodin and ended up in rehab three times. I just hated myself.”

The petite star dropped 50 pounds while filming “Dancing With the Stars” and in the months after to eventually reach 112 pounds.

Osbourne adds that she broke down in tears twice over her new bikini cover with Shape magazine — once when she shot the images and again when she saw the cover come out.

The shoot was the first time she has ever worn a bikini.

“I used to eat chips and cookies and drink soda all day long,” she said. “I had to start making better choices.”

“I understand that being judged by others comes with the territory, but it broke my heart and ruined my self esteem,” she admitted. “It sets you up to hate yourself in a huge way. I was so angry about the things people said about me. I truly believe it’s the main reason I turned to Vicodin and ended up in rehab three times. I just hated myself.”
