Friends and family of party-animal actress Lindsay Lohan are worried she is suffering from an eating disorder. The starlet has recently lost about six kilograms, despite previously denying she had a problem when she first dramatically lost weight. A close source reveals, “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.” The star has dwindled from a healthy size 10-12 to a tiny size 6.
