i think part of celebrity media training for red carpet / promo photo ops involves conditioning facial expressions to consistently hold something like "neutral/pleasant" because the photos are constantly snapping and any photo looking sufficiently weird is gonna be the one in tabloids for "REHAB RUMORS" headlines.

and she's one of those people with eyelids partially closed when at rest. i am also one of those people. i lack media training, so candid photos of me look like i'm disgusted, while photos where i open my eyes and try to smile look like the arrest photo for a guy who was caught sleeping in a stolen cop car with a trunk full of partially cannibalized policemen.
