The 23-year-old opened up for the cover story and shared that despite attaining praise for maintaining her 69 pound weight loss and going through the emotional process, she will always remain humble.

'I'll never be the kind of person who thinks, 'I'm so hot,' " Osbourne told the magazine. "I don't want to be. But I learnt to respect and love myself - something I didn't think I would ever be capable of."

"At the Emmys last year I had my first moment when I really felt good. I put on my dress and when I looked at myself in the mirror I cried," she added.

The lavender-haired former wild child reportedly shared how hard it was to begin exercising when she first started working toward living a healthier lifestyle.

"When I started exercising I couldn't even do one sit-up! By the end of the first week I could do three," she said. "Now I work out every day and I just don't feel good if I miss it. It's amazing how quickly your fitness builds, but you have to really want it."

Osbourne, who dropped five dress sizes during her stint on "Dancing with the Stars" in 2009, said exercising can be grueling but in the end worth it. She said she is "miserable" for the hour that she exercises but when she is done she feels amazing. Exercising is "no quick fix," she noted, and takes a long time to see results, but it is worth it in the end when the weight sheds off.

The "E! Fashion Police" co-host also shared that balancing eating right and exercising helped keep the weight off. She said solely dieting helps lose weight but not keep it off.
