Lindsay Lohan seems to be flaunting her bony body at every opportunity at the moment.

Last week the formerly-curvy actress was a sight for sore eyes in a backless white dress that hung off her skinny, pale frame during a shopping trip with sister Ali.

And on Sunday she was at it again, hitting up Gucci and Louis Vuitton in Maui dressed in denim hotpants and a skimpy summer top that she let fall from her shoulders to reveal her protruding rib cage and jutting shoulder blades.

Lindsay's weight loss has been used as further proof of her supposed downward spiral following her split from girlfriend Samantha Ronson, with insiders claiming the rehabbed star has turned to booze and partying to help cope with the break-up.
