Kelly oozed sophistication in a stunning white dress as she posed on the red carpet in Sydney, Australia.
While the layered white frock accentuated Kelly's curves, it was sheer enough to show off her cleavage and white bra.
Kelly teamed her frock with black heels but kept accessories to a minimum. Her vibrant purple locks looked sleek as it draped over her eye.
Kelly, 29, will be joining the panel alongside host Jennifer Hawkins and regular judges Alex Perry, Didier Cohen and Cheyenne Tozzi.
It seems Kelly is the perfect person to take up the guest judge role too, as she's making quite a name for herself in the fashion world.
Not only is Kelly co-host of popular US show Fashion Police, in which she discusses the latest red carpet and every day fashion trends of Hollywood celebrities, but she recently unveiled her first clothing line, Stories...by Kelly Osbourne.
