Maybe it's this old clip: https://www.youtube.com/watch?v=niQq2dWwwrU&t=1m30s -- hope there's a better quality version somewhere. Whenever a celebrity gets messy they just seem hotter to me the next time I see them, and this lady has been messed up a lot! I call it the "Natalie Wood Effect".
Great video. Never seen it before. Kelly has been pied and slimed so much that you have to suspect that she likes it. Well I'm going to pretend in my mind that she does anyway
