Lindsay Lohan is back to her old braless tricks.

The Mean Girls star stepped out unsupported when she hit the supermarket in Malibu with her sister Ali yesterday - and in her thin vest top left little to the imagination.

Lindsay - whose weight has fluctuated over the years - looked thinner than ever, showcasing her scrawny arms as she paid for her items at the checkout.

Without her curves, Lindsay looked half the woman she used to be.

We hope she hasn't rejoined the super skinny brigade.
