I think it is too easy to call her a "celebrity".   Anyone who has seen "Frida" knows that she is a skilled actress. Watch her on "30 Rock" while you can - she is playing a wonderful role as Alec Baldwin's girlfriend.

Harry Chapin was a wonderful musician who used his fame for good. He would always say that he would do a concert one night for himself and the next night the concert was for the other guy.   He cared about his career but he also spent considerable time helping others.   Selma Hayek is following in the footsteps of artists like him - and Danny Kaye who did an incredible job of promoting UNICEF and their programs. Now Selma Hayek is working in a similar role with UNICEF.   

It would have been easy to turn the camera off when she was breastfeeding, but I truly believe she knew that seeing the images would get people talking about a situation (in Sierra Leone) as well as breastfeeding - subjects that are not glamorous newspieces.
