Have you ever noticed that celebrities walk with their heads down a lot?

[mizzhollywood26]

not like they're hiding, but like they're looking at the ground a lot.

like when they're just walking around minding their own business and don't know papparzzi is around. not when they're at a premier or something.

They are avoiding having their picture taken by the ever present press.

They are trying not to get their pictures taken

They do that so the paparazzi wont take there picture plus they don't want to answer questions about them being in the tabloids.
