Celebritys selling pictures of there babys

this is a very interesting thing going on in Hollywood where the rich and famous agree to sell pictures of there new borns and cash in on it. now quite a few celebritys donate the money to charity but it got me wondering does everything in Hollywood come with a Price or what? i mean is there no Privacy or being low key left? recently Brad Pitt and Angelina Jolie sold pictures of there babys for a whole lot of money which went to charity. i guess this is better than having a stalking camera man snapping pictures and given them directly to the star magazine or the national enquier,etc... but when a Celebrity asks for Privacy and wants things to be granted and then allows pictures and things inside there world then they have given up something don't you think? I just wonder what it really means to sell pictures of your family like that. i guess i question the motives. but everybody and everything has a price tag.
