The actress, who already denied rumours that her thin frame stems from eating disorders, is once again worrying her friends, who have seen her weight yo-yo from sizes 10-12 to a size 6 or less, reports FemaleFirst.
A source said, "She is thinner than ever and we are concerned she is taking it too far. Lindsay’s weight has always fluctuated, but since falling in love with Samantha Ronson – who is naturally very slim – Lindsay seems desperate to lose more weight."
Lohan, however, insists on the fact that she is following a healthy diet.
