Demi Moore Shows Signs Of Stress

Demi Moore's usual youthful glow is fading!

Looks like the stress surrounding her alleged marriage drama with Ashton Kutcher is quickly aging the 48-year-old actress.

While leaving her favorite nail salon in LA, the Ghost actress sported a snug sweater, red Kabbalah string and her wedding ring. Seems as though Demi is still holding out hope that she and her younger hubby will weather the storm.

On Thursday, Ashton decided to quit Twitter after getting bashed for supporting Penn State's Joe Paterno. From now on ... instead of writing his own Tweets, the Two and a Half Men actor will have his management team monitor his account.

With Twitter out of the way, perhaps Ashton and Demi will have more time to focus on each other.
