The scratches and what looked like a figure-of-eight burn on her right forearm were revealed as the 20-year-old starlet left a showbiz bash reports Sun UK

Shocked experts said the gouges bore all the hallmarks of a condition that afflicts increasing numbers of youngsters.

Mean Girls star Lindsay, who has battled anorexia and admits to taking drugs, also wore a plaster on a right finger at the party - which followed the World Music Awards on Wednesday at London’s Earls Court.

Expert Jan Sutton, who has written two books on self harm, said grimly: “The photographs have all the telltale signs.

“The arms are the most common place for self injury.

“Some of the scars are fresh and just above those there are a number of injuries which look older. They are called keloid scars and are just beginning to disappear. It would be difficult to argue this is an accident as there are just too many scars.�?

Lindsay has told in the past how she feared she would die after years of punishing her frail body. She recently confessed to having “hit rock bottom�?. Last July she was taken to hospital while shooting her latest film Georgia Rules.

Lindsay admitted her eating disorder had returned to plague her, saying: “I was making myself sick. Sometimes being that thin doesn’t look healthy. I kind of didn’t realise that.�?.�?
