The middle child of Sharon and Ozzy turns 28 today! Kelly Osbourne basically grew up before the eyes of the American public, having first won us over on The Osbournes reality show in 2002 alongside little brother Jack and the rest of the family (dogs and all!). Ten years later, Kelly's all grown up and has made quite the name for herself in fashion circles, as co-host of E!'s Fashion Police and a regular red carpet commentator at awards shows like the Emmys. She is also known for her head-turning purple hair, which she matched to her dress at the aforementioned ceremony in September. Here's wishing Kelly a very colorful birthday!

Plus, see more stars with rainbow hair!
