Katherine Heigl should have the natural look down pat. Rising to fame as "Izzie" Stevens on Grey's Anatomy, her portrayal of a hard working doctor should have involved looking realistically worn and tired. The trouble is that she left the show and went into romantic comedies such as Knocked Up and 27 Dresses.
She must have gotten used to looking like a 50s movie starlet, because she hasn't quite remembered how to look good without makeup. The blanket, bags under the eyes, and haunted look makes her seem like she's just been rescued from a sinking ship. Grey's Anatomy is still running, though. So she might be just preparing for a return. In any case, we don't mind Katherine without her face all caked up - she has been blessed with extreme natural beauty and we admire her for it.
