Mischa Barton, Lindsay Lohan and Katie Holmes are the latest stars who seem to be shrinking before our very eyes.

The former OC star stepped out at Paris fashion week looking painfully thin, amid reports she has dropped three dress sizes in just a few months.

Mischa also looked to be back to her hard-partying ways when our spies spotted her looking worse-for-wear at an L.A nightclub at the weekend.

But she isn't the only star that is looking like a shadow of her former self.

Superskinny Lindsay shocked onlookers when she revealed the dramatic extent of her weight loss back in January.

And it seems that even Tom Cruise's missus is flaunting the skeletal look.

Katie looked frail and gaunt towards the end of her stint in Broadway play All My Sons at the start of the year, and put in a painfully thin appearance alongside her husband at the Brazilian premiere of Valkyrie recently.
