No way. I'm going to a party in the county jail.
Every year the Sunday Times publishes a Rich List. Every year celebrities Do Stuff for charity. We know about these things because they are in the newspapers and on TV. If someone very wealthy or very well known does something - anything - for charity, we often know about it.
It's also unfortunate. Because if WE can read that information so can about 60 million other people. "Hey look! Elvis just funded Greenpeace because he wants to save the whale. I do sort of environmental stuff (well I work with donkeys) - maybe he'll fund me too!"
