They may be royalty, but in this respect, they're like everybody else.
E! News has obtained an exclusive photo of the pregnant duchess's blacked-out van as it arrived around 6 a.m. at the Mary Sandford entrance—which is the hospital's back door—accompanied by a lone security car.
By the time this image was taken, Kate had already been whisked through the door and into the Lindo Wing where she's due to give birth to the royal baby any time now.

Here's a couple of more photos of the duchess' vehicle and its escort.
