Does Suri Cruise really exist?

If you're a celebrity, you can't avoid the paparazzi. How then have Tom Cruise and Katie Holmes managed to keep their precious bundle Suri Cruise unphotographed? Typically, celeb parents are photographed taking their baby for a walk but protect them by covering the stroller, carseat or the baby itself with a blanket. Yet from the lack of photo evidence, it does not appear that Suri has ever seen the light of day. Even if she has been outside on Tom's property, you'd think aerial photographers would have captured a fuzzy image at least.
