Rumer Willis strips down to undies for racy photoshoot

Rumer Willis has stripped down to her underwear and bra for a racy photo shoot with celebrity photographer Tyler Shields.

In one of the pictures, the eldest daughter of Demi Moore and Bruce Willis shows off her flat, toned abs and long legs as she kneels on the ground, her arms outstretched and holding onto some sort of rusty saw, Us Magazine reported.

The 25-year-old actress also took to Twitter to say that she was getting her hands dirty at a photoshoot with Shields.

Another pic in black and white, features the 'Sorority Row' star perched in profile on a rock with one leg outstretched in front of her, while the bent at the knee, as she stares over her shoulder into the camera.

A third pic shows Willis reclining directly below the camera and gazing up into the lens, as her body is visible only from the waist up.

A fourth picture shows a close-up of the star's face as she looks over her shoulder at Shields, while her dark, auburn hair is pulled back into a ponytail, exposing part of a tattoo on her upper back.
