To celebrate Kelly Osbourne’s 26th birthday, I have a small challenge for you: I dare you to find someone who has changed her look more than this rock princess. From her days as the goth/punk progeny of Ozzy and Sharon on The Osbournes, to her sleek, refined appearance now, there’s nothing Kelly hasn’t tried — racoon eyes, mohawks, fuchsia lips and retro curls are just some of the styles in Kelly’s beauty archive. Check out her transformation!
