The English actress boasts such a youthful appearance as she looks like she’s in her early 20’s rather than her actual age of 29. Unfortunately for her, this may not last for very much longer.

Knightley has battled anorexia in the past, and some critics believe that she smokes to keep her weight to a bare minimum, but there is no real proof of that as it is all hearsay. What is not hearsay is the fact that she’s constantly seen puffing away at restaurants and bars.
