Kelly Osbourne in a Purple Dress at the Emmys 2012

Kelly Osbourne reported for duty on the Emmys red carpet this evening. The Fashion Police cohost chose a lavender Zac Posen gown for the event, which perfectly complemented her purple-streaked hair. Kelly will be busy with her E! hosting duties tonight, along with Giuliana Rancic and Ross Mathews. We're also keeping track of the stars as they arrive in our own Emmys live show.
