Demi Moore’s frail and gaunt and appearance in recent weeks has caused considerable concern.
The mother-of-three, who announced she was divorcing husband Ashton Kutcher last November, has lost a considerable amount of weight over the past four months.
Demi Moore last appeared in public on January 14 at the Cinema For Peace event at the Montage Hotel in Beverly Hills.
Her frail appearance shocked fans, although she appears to have been loosing weight steadily since claims emerged Ashton Kutcher had cheated on her with 22-year-old Sara Leal.
Demi Moore, who looked a shadow of her former self, wore a slim fitting black dress which showed just how much weight she had lost from her usually toned physique.
On November 17, 2011, Demi Moore announced that she was filing for divorce from Ashton Kutcher after six years of marriage.
In a statement Demi Moore said: “It is with great sadness and a heavy heart that I have decided to end my six-year marriage to Ashton.
“As a woman, a mother and a wife there are certain values and vows that I hold sacred, and it is in this spirit that I have chosen to move forward with my life.”
While Demi Moore is seeking treatment, Ashton Kutcher is currently in Sao Paulo where he has been attending the Fashion Week.
Yesterday Ashton Kutcher shared a snap of himself joking around pretending to surf on a street during a spot of rain.
Ashton Kutcher is also said to have moved on following the breakdown of his marriage to Demi Moore.
The actor is now reportedly dating screenwriter Lorene Scafaria, who, at 33, is his own age.
The pair spent Christmas together in Europe.
Earlier this month, Demi Moore was seen in a parking lot with a 26-year-old actor and personal trainer Blake Corl-Baietti.
Her reps refused to comment on speculation that the actress was in a relationship with the younger man.
Demi Moore recently opened up about her fears and heartache in an interview with US Harper’s Bazaar.
She admitted: “What scares me is that I’m going to ultimately find out at the end of my life that I’m really not lovable, that I’m not worthy of being loved.
“That there’s something fundamentally wrong with me.”
