Lindsay Lohan has once again sparked rumours that she is suffering from an eating disorder after shrinking to a tiny size 6. 

The Mean Girls star stepped out looking skinnier than ever as she arrived at LAX airport with girlfriend Samantha Ronson.

Wearing skin-tight leggings, the actress sported much thinner pins than her usual shape.

Yet, according to reports, Lindsay is adamant that she eats a healthy diet of sushi, smoothies, fresh fruit, vegetables and green tea.
