Despite the general public thinking that Keira Knightley must be anorexic because of how thin she is, Keira's mother insists that she "eats like a horse" but remains so thin because of genetics! Specifically, OK! Magazine reports
The waif-like Pirates of the Caribbean star has been dogged throughout her career by false claims that she has an eating disorder...
Now Keira's screenwriter mother, 57, has told Britain's Sunday Times newspaper that her daughter has simply inherited her father's stick-thin figure.
Sharman MacDonald told the paper that Keira's dancer dad, Will Knightley, 62, has always struggled to put on weight and that the actress also has to "eat like a horse" to stay at healthy size."
Wow, I guess some people just simply can't put on weight, and Keira Knightley clearly is one of them! I can't believe how brutal Hollywood is... they rip apart the fatties for being overweight and they're equally insensitive with Keira because she's too thin! You just can't win sometimes in this world! Frankly, I think Keira's hot! And I believe that she's just naturally thin! So HA!
