The Stunning Transformation Of Kelly Osbourne

If multitasking had a face, it would be Kelly Osbourne. At 24, and with a renewed sense of purpose, she was crushing it. The multi-talented star took hosting gigs around the world, along with acting roles, radio spots, magazine columns, music writing, theater, film, and TV gigs.

She got engaged to model Luke Worrall in 2008, which she would later break off in 2010, according to PEOPLE. And she even returned as herself, once again, on family reality reboot Osbournes: Reloaded. She appeared to have it all. But something was still missing.

The newly sober icon revealed to Cosmopolitan that she was using food for comfort: "I hated the way I looked but I couldn't mask my self-loathing with pills anymore."

She was even was experiencing fat-shaming from other celebs. On air with Fashion Police in 2011 (via Us Weekly), Osbourne fired off about Christina Aguilera saying, "she called me fat for so many f***ing years." Not one to keep her thoughts a secret, she also shot back at the media, "I took more hell for being fat than I did for being an absolute raging drug addict."
