Keira Knightly was spotted at Calgary International Airport in Canada munching on a cookie, carrots, an apple, a latte (or tea)...and even her fingernails!

So either the beauitful actress was waiting a really long time before a flight, or maybe the airport is the new place to hang rather than Starbucks.  Whichever, some of the photos I think looks like they should be an ad for a magazine.
