After ruling the ramp for nearly 20 years, it seems that time is taking a toll on supermodel Kate Moss.
Moss arrived at Sir Paul McCartney's 65th birthday party in a dress that revealed a pair of "worryingly" thin legs.
The dress, a cream Old Hollywood-style garment, is undoubtedly Moss' favorite, since it was worn by her on her own birthday in January. However, this time it was not stunning at all, as it exposed her bony and sinewy legs.
Sun doctor Carol Cooper expressed worries that Moss, who was not accompanied by her substance addicted boyfriend Pete Doherty, is overlooking her health.
"She's abnormally thin, worryingly so. You can see the outline of muscle on her thigh because there's so little fat now," The Sun quoted Cooper, as saying.
"We're used to seeing her slim, but this is the thinnest I've ever seen her. This looks like a young woman who's neglecting herself. We know she doesn't exercise much so she must be eating very, very little," she added.
Cooper added that Moss' terrible condition was a result of "stress, depression, drugs and alcoholism."
"Stress, depression, drugs and alcoholism can often be behind not eating enough and losing weight. Kate looks too frail to stand unaided. Her head is disproportionately large and too heavy to keep up," she said.
"She's never been big busted but now she's completely flat-chested. You can see her ribs," she added.
Psychologist Deanne Jade, of the National Centre for Eating Disorders, said that Kate's pictures were expected to end up on pro-anorexic websites used by girls who support each other to go hungry.
"Images like this add to 'thinspiration' and a belief that to be successful you must be worryingly thin. People like Kate don't take responsibility," Jade said.
