The 25-year-old daughter of the 'Die Hard' actor and his ex-wife Demi Moore posed for Shields' latest series, in which she is snapped looking seductive among dirt and rocks, reported Contactmusic.
In one photo, Willis is kneeling on the ground, arms outstretched and holding a massive rusty saw by the handle, while only wearing her lingerie.
The singer-actress took to Twitter to post the preview shot from the session and wrote, "Getting my hands dirty at my shoot with Tyler Shields."
