She was left devastated by her split from girlfriend Samantha Ronson earlier this month and now it seems Lindsay Lohan's heartache is taking a physical toll too.
The Mean Girls actress looked skinnier than ever as she hit LA's Melrose Avenue for an afternoon of retail therapy with her 15-year-old sister Ali.
Her cream halter-neck sundress hung off her rail-thin frame with the cut-away back revealing her protruding ribcage and sinewy arms.
The 22-year-old looked on edge during the outing, clutching a can of Coca-Cola and biting her fingernails as she stopped to try on reading glasses at an optometrist.
Lindsay's weight has yo-yoed dramatically over the years from buxom to skeletal. Mail Online reported.
Her current appearance is reminiscent of her look in 2005, when a friendship with Nicole Richie and super-skinny stylist Rachel Zoe saw her weight plummet.
