Today, October 27th, our very favorite Osbourne turns 27. During her time on The Osbournes, her family's foray into reality television, we were all privy to Kelly's fashion growing pains. Her look was constantly changing, including her hair color. In the past few years, she has identified a signature style that's mature while still being young. She strikes a personality and age appropriate balance between her goth/punk roots and Hollywood glamor. A pro at pairing a bold lip with an unexpected hair style (we're loving her current lavender-grey), Kelly has become one to watch on the red carpet.

So wish Kelly a happy golden birthday and take a look through her changing style.
