When she promoted her new perfume:

For a girl that doesn't just want to respected for her cup-size it has been a good move to try something new. Being a mother it has advantages when your kids will eventually believe that you are more then just a lustobject for geeks and freaks, roaming the internet for gigantic breasts.

Not that I think people will ever love her for anything else, but hey.........
The Beckhams did it, Beyonce has one......why not the Lolo Ferrari of 2008.
