Jessica Simpson - breast implants?

Has Jessica Simpson had a breast augmentation? The above photos are from the most recent issue of In Touch magazine, where I was interviewed on this very topic. It appears that after her very public breakup with Nick Lachey, she has undergone a change in her breast size. The above photos show her in the same outfit, before and after the breakup. It does appear to me that her breasts have increased in size from a C cup to a D. There are many actresses who undergo changes in their breast size (such as Pamela Anderson and Britney Spears), both making them smaller and larger by likely exchanging implants for different sizes. It is possible that after her recent documented weight loss, she had lost size of her breasts and has had her previous implants replaced with larger ones.
Most women who undergo breast augmentation fall in one of three groups: (1) Those who are usually in their twenties, have never had large breasts, and are finally at the stage in life when they can afford them, (2) Those who are usually in their thirties, have finished having children, and would like their breasts to be like they were before breast feeding and pregnancy changed them, and (3) Those women who have recently become divorced and are looking to improve their self image as they re-enter the dating scene. Is it possible that Jessica is one of the third group??
