During a recent shopping with pal Mischa Barton, she again shocked onlookers when her skin-tight orange dress revealed a concave chest and protruding hipbones.
The star, who had appeared to have gained a few extra pounds in recent months, now looks to have dropped back down to a worrying low.
Reports were circulating in the US that she had briefly checked into California's Beau Monde Treatment Centre.
Her publicist said: "She is not in rehab she is at home in Glendale. Sobriety is an ongoing process but she is sober".
Last year, the 25-year-old confirmed that she had sought help for what her spokesperson called an inability to put on weight, but denied it was treatment for an eating disorder.
Is it just me or are you disgusted by these pictures. She actually looks bloated around the middle the way some third world child or youngster would be that is suffering from malnutrition . She looks utterly shocking and her eyes and face in general has no signs of life at all.
