Zoom in here, and you see that the thumb nail left has a massive damage (rib crosswise).
Maybe that's one reason for the way she usually grabs her clutch, with the thumbs in the back and all eight other fingers in front: to hide the thumbs.
Could be artificial nails disaster, but who knows? Malnourishment
can also cause nail damage like ribs (crosswise or along) or white spots, or part of the nail peeling.
Most likely, as she's never had artificial nails and always kept them short. So if the nails are damaged and she's not actively damaging them (biting, artificial nails, etc), then it's poor diet or health, likely a combination of the two, her diet must have by now wrecked her health quite a bit. And if the drinking rumours are true, well...
