Are Heather Graham's breasts shrinking? Is that legal in Hollywood?

Heather before Heather now

Turns out that Heather Graham's lovely breasts are -- in all probability -- natural.

Why?

Because judging by this photo of her from last night's premiere of "The Hangover," right, they seem to have gotten smaller, compared with the photo on the left taken several years ago.

This is something that only happens to natural breasts, not faux Hollywood breasts.

Kudos, Heather!

 You will not believe the change....
