Uh.. yeah. She is a celebrity. the definition of a celebrity is a famous or well known person. Sarah Palin, John McCain, Barack Obama, Joe Biden... are famous and well known... They are CELEBRITIES. Whether they like it or not they ARE celebrities.
Now... that's not to say that ALL celebrities are like Paris Hilton (although she seems to have grown up as of late but there is no telling with her). Some celebrities are good, down to earth people... some are spoiled, high and mighty pompous boneheads.
ETA: I wonder if it would be better to donate and just sell the clothes in the store... or for them to sell them like they did the scarf and pin and collect the money and put it towards the shelter and the meals on wheels. I think selling the clothes and putting the money towards other things would do more than just selling the articles of clothing in the store. Imagine the money that they could raise.
