Faceless Aliens Spotted at Wimbledon Tennis Tournament

From England's Daily Mail, here are images of a pair of faceless "aliens" photographed at the Wimbledon tennis tournament, and shopping around town in London. Are they otherworldly beings plotting a takeover of Earth, or are they just tourists?

Some have speculated that these faceless folks are just people playing a prank or are maybe celebrities fed up with being recognized by the papparazzi.

I report, you decide!
