It's obviously photoshopped - take a close look at the head-to-body proportion. Also, Ms. Parker can be seen in a bikini scene in the movie Race With the Devil, and, well, how to put this, while she has her own marvelous body, her "Tower Rooms" are not as, um, spacious, as in this photo. Still, whomever did this has paid a very nice tribute to her, knowing that she was, is now, and always will be gorgeous.
